I’m redesigning an old app according to a dribbble shot: [![](https://cdn.dribbble.com/users/4601337/screenshots/15921850/media/11b4d473412c41b7c6dcba64d48914bd.png) ](https://cdn.dribbble.com/users/4601337/screenshots/15921850/media/11b4d473412c41b7c6dcba64d48914bd.png) This is what it looks like: ![Screen Shot 2021-09-14 at 2.43.26 PM](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/a/1/a121ad53d0812bce3901cc2d9d6d564039b43c3d.jpeg) I’m using the MealDB API. However, the correct number of ingredients just won’t appear. Sometimes, I see the same ingredient repeated 20 times, with the ingredients starting at 1 and increasing by one with each DVL display. Other times, every single display has 22 ingredients, which isn’t correct. Here’s my code; ![Screen Shot 2021-09-14 at 2.45.49 PM](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/7/6/76f258d2cda33077608e15c725f745b017aa21d9.png) ![Screen Shot 2021-09-14 at 4.05.43 PM](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/5/a/5aa9e9831b6db0b26db51828a02a33e6dcbbe09d.png) ---

I figured out the issue but can’t think of any way to rectify it. So basically I had created a list with all the letters of the alphabet. I wanted to loop through those letters and put them one-by-one into the search MealDB by first letter API. I’m not sure for the j loop probably is asynchronous or something and looping through 26 letters and then calling an API 26 times was probably too much for the app. When I tried searching only by letter a, I was able to see all the ingredients and names properly. When I tried searching by a then b (just 2 letters), the app mixed them all up and then wasn’t able to find the correct number of ingredients. Any suggestions? ---

Remember that `create row` is an asynchronous block which means, if your loops are fast enough you will be mixing values. ---

Ohhh, I forgot about that. So how can I rectify it? ---

I would say that you need a variable that you set to `null` with every start of the main loop and in the `create row` block set the variable to the `row id` returned by the block. In your loop you need a wait loop to check that the control variable is not null which means the create row operation is completed. I hope you get what I mean because I was just brain dumping. ---

I was referring to something like this > [@Is there a wait until block?](https://community.thunkable.com/t/is-there-a-wait-until-block/1484665/6): > > I would do something like this [image] Although in practice I will also exit the loop after some seconds even if the control flag is still false. ---

@codeswept Which url are you using from [the documentation](https://www.themealdb.com/api.php)? And which property is not getting counted correctly? Is it “stringredient” or something else? ---
