Hi all, I’m trying to develop an app similar to that of a shopping list, except the user chooses from existing items (restaurant menu items). This data is up on the airtable and that is working fine. The problem I’m having is in showing the selected items in a list. Here is an image of how I want i…

Hmm, so if the code looks correct, where do I go from here? Thank you for taking a look, I really appreciate it! If needs be let me know if you want the link to the project!

There are other factors that can affect correct code blocks. As a somewhat extreme example, if you were running an endless loop (e.g. forever block) that was constantly changing/retrieving data within the same screen, that might be enough to take up all of the device memory allocated to Thunkable an…

I suspect there is something else going on in the project which is preventing it from working as expected. @tatiang is correct, looking at the project is likely the easiest way to help you. If you don’t want to share it publicly you can send it to me in a private message and I’ll take a look. As a …

So this does work for me: [I can share the project link but without my Airtable API key and base ID, it’s not very useful to see.] [shopping list demo] [Screen Shot 2020-01-21 at 9.40.26 AM]

You’re using app selectedList as the columnName input for your spreadsheet but it doesn’t look like you’re giving it a value (besides the invalid item block). Try setting the columnName to a text string, as I’ve done in my example. I’m actually surprised you’re able to pull any data into the top li…

Thanks for this info, weird that it isn’t working on mine! I don’t have a forever block as far as I’m aware - if you’d like to look at the project is it best to paste a link publicly here? I’m totally new to all of this as you can probably guess! The app selectedList is so that it presents data from…

Okay, that makes more sense. Again, initializing a variable to “item” doesn’t do anything and should probably be avoided. But now I see where you are assigning item to the app selectedList variable and that looks fine. Sharing a link publicly as a non-pro user is really up to you. It does draw atte…

I just noticed that you are initializing app selectedList on the item select screen. I would delete that entire block and see if it fixes things. If not, then seeing your project would give me a big-picture view of how you’ve organized things. Edit: see my response below – you may not need to delet…

Better yet… you’re assigning an item (text string) to a list variable. What you really need is a separate variable called app columnName (or similar) that stores the item on the previous screen. Then, use that variable for the column value when you call Get Column. And initialize app selectedList to…

You have conflicting blocks: [Screen Shot 2020-01-21 at 10.44.23 AM] I honestly have no idea if telling the compiler to do nothing and to simultaneously do something when an item is clicked can cause problems but I’d definitely rule it out by deleting the blank blocks.
