Hi! I want to get a special item from a json file. The url for the json is: [https://corona-ampel.gv.at/sites/corona-ampel.gv.at/files/assets/Warnstufen\_Corona\_Ampel\_Gemeinden\_aktuell.json](https://corona-ampel.gv.at/sites/corona-ampel.gv.at/files/assets/Warnstufen_Corona_Ampel_Gemeinden_aktuell.json) I want for example the “Warnstufe” from “Name”: “Rust” from the last date. Hope somebody can help me how I can solve this. kindly regards ---

This works. You need to test it on a mobile device with Thunkable Live. If you preview it in a web browser, it will give you an error. Here’s the project: [Thunkable](https://x.thunkable.com/copy/524e165e99bbea9545fe8e8ae6f580ca). ![Screen Shot 2020-09-27 at 8.33.13 PM](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/b/c/bc72ad7365e49ac2ab48706c3e90921633ef0b3a.png) ![IMG_D0CACE51BC9F-1](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/5/6/56660ccd1b7e289cbebe7bdc180a0f767bb595f6.jpeg) ---

Thanks for the answer and project. Is there any possibility to search for an other city for example vienna or graz … to get the actual “Warnstufe”. kindly regards again ---

If you’re going to get different data from a JSON file, you really need to understand how they work. I won’t be able to make a demo for each value you need. There are many tutorials available (I Googled _thunkable json_). If you are having trouble with something, post a screenshot of your blocks and someone can help you. ---

Thanks for your answer. In my opionion I will need a loop for the name label to change the 2 in an index beginning with 1 to 2095 to search for a special name. ![Unbenannt](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/8/a/8a77152f0b3d0841bed3ecc4a476a21d1efe17af.png) maybe somebody can help how I can change this in a loop. kindly regards again. ---

How familiar are you with Thunkable? Which loops blocks have you tried already? I think you’re going to need to use the _Count from 1 to length(list)_ by 1 block. ---

Thanks for the answer. I have tried the following code: ![thunkable_corona](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/6/8/68f2de4fd9f1fdb7a5d047a20551be8843e38c0e.png) Here my project: [Thunkable](https://x.thunkable.com/projects/5f71a5eea251c564f3d4abd1/57a6b7ed-c075-4536-bb58-1f775c20cdc8/blocks) But it doesn’t work. Hope somebody can still help me. kindly regards ---

That’s a good start! I’m trying to publish some changes I made to what you posted but the publishing server doesn’t seem to be working for me. It just says “Processing…” Some things I noticed about your blocks: 1. You have “If Status=200” twice. I guess I had that in the original project too. Oops! You only need it once. 2. In your count with i from 1 to 2095 loop, you’re getting the property of list item # _app nr_ but there’s a good chance that _app nr_ will be zero/null many times in that loop. So you need to check to see if _app nr_ ≠ 0 first and then change the label text if it’s not zero. That’s what I was trying to fix and publish to show you. 3. The _from JSON Status label set Text to Done_ block should be at the end of the _If status=200_ section not below it. That was my fault, too! ---

Okay, try this: [https://x.thunkable.com/copy/e2a8da3e6387e7b2210f1a581d1eb44f](https://x.thunkable.com/copy/e2a8da3e6387e7b2210f1a581d1eb44f) ![Screen Shot 2020-09-29 at 3.51.03 PM](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/8/2/82588b3dcd0a0b6e8cc0b1d8ae63d419dcdce631.png) ---

If you know there is only one name that matches your search (“Weiz”), you can make this much faster by adding a _break out of loop_ block from the _Control_ drawer right after the _set app nr to i_ block. So if the JSON record with the name “Weiz” is #15 out of 2095, it will stop when it finds it. In that case, only 15 loop cycles/iterations will have completed instead of the total 2095. ---

Thanks a lot for your answer. I want to upgrade this project and try to change the background-color of the warntufe label regarding to the value. I try the following after web\_api get: ![grafik](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/1/c/1c64b5f8347bff5253f85f3c8af667fc37aff156.png) But when the warnstufe text is 4 the background color will not change to blue. Hope somebody can still help me there. kindly regards ---

You need to put the if/do block INSIDE of the Web API blocks’ “then do” section. The way you have it set up is like telling a kid these three things: 1. “Tell me your name.” 2. “Solve 18 \* 45 \* 3 in your head.” 3. “What’s your favorite color?” Because they are going to take a while to solve #2, they will probably tell you their name first, then their favorite color, and finally the answer to the math problem. Web API calls take a little time. But the compiler is going to go right past to the next statement (if/do) unless you either make it wait or you put it inside the “then do” section of the Web API block. ---
