Hi! I wanted help creating a nutrition app. I want my app to use an ocr scanner but instead of giving a decription i want the ocr scanner to read the image and let the user know if it is healthy or not.

I can help you get a single property and then you can look over the documentation, tutorial videos, etc. to learn about the rest. Be aware that a property with square brackets [2] indicates a JSON array which is handled by list blocks in Thunkable. And I mentioned this before but JSON/API data is d…

I know that you want a simple fix for everything but there are a lot of problems with the way you set up your code. I can’t solve it all for you and some of this is just taking the time to learn to program. The reality of coding is that if you change one little thing, it then affects everything else…

Okay. Thank you for helping me out! I’ll fix those mistakes. I had a quick question. I know I would set the variable carbs to get the json response, but what would I set for the variable “message”?

So instead of running the entire set of blocks and wondering why it doesn’t work, you can debug your code by adding “set label’s text to” blocks every so often and checking values that you are getting from blo…

Is there still an error with the way this is set up? When I live test it says there is something wrong with the blocks. [image]

Yes, it’s still not correct. Please watch my API/JSON tutorial video to see how to set up the “get object from JSON” and “get property of object” blocks and how my if/else blocks are structured.

Thank you for all the help! I’m going to work on it and I’ll show you what I come up with in a couple of hours.

Should it be something like this? [image]

Can someone please help me fix these errors, I need to finish this app today?
