The screenshot below has Gallery1 in which is TextInput1
that contains the 'Unique ID'. I have added a button in
Gallery1 I could use ThisItem language to capture Gallery1
data for use in another screen.

Is it possible to write a variable in the 'Client Attachments'

button on the left margin that capture the 'Unique ID' from

Gallery1 and then use that variable to auto-populate the

default state of a ComboBox in the second screen?

Auto-populate Gallery1 'ID' field content from above into

ComboBox below.

Hi @Phineas ,

I will show you but also explain it can be done a little different just for learning purposes.

Also your code for your combo is confusing because you are doing a Distinct, which works on an entire field, so you will get multiple results and something normally for the items property.

For Screen 2 are you trying to Select the Default item/Selected Items of the ComboBox based on the ID from Screen 1(Gallery 1)??. Thats different then saying populate a combo box with (selectable items) AKA the items property.

Which one do you want??? a Default selected based on Screen 1 or the Items property filled based on Screen 1??

That side for a moment lets talk about passing the data to Screen 2

1. you do not need to capture the value in a variable at all. When you do that, especially since you are making it Global, its automatically available everywhere.

Treat this value as a Context value from screen to screen.

So dont use the global variable, just do this

Navigate(Screen, Transition, { IdToSendToScreen2: Gallery1.Selected.IdColumn })

Now in screen 2, use the (I made it up) Context Variable IdToSendToScreen2, inside the items formula or the Default/DefaultselectedItems formula to auto populate the selected item.

and now you dont need to use a global variable.

If I have helped you, I would really appreciate if you please Mark my answer as Resolved/Answered, and give it a thumbs up, so it can help others

Cheers
