Setting value based on global variable

I have a number field in my app. To choose what number to insert, the user has the option to click on the field's text, that navigates the app to a screen with a set of pictures and for each picture there's a number. Clicking on a picture sets a global variable to that number and then that number should be put into that field. The thing is that no matter what, it doesn't seem to work.

I don't where I should put that global variable because it either resets to what there was before or it changes for all the items in the list.

I figured it should go in the default of the datacard or the default of the datacardvalue or in the update.

Please help me, I'm at a loss

Hi @msabau ,

So, if users have not selected a picture, it should be the default value, otherwise the variable instead:

If(IsBlank(Variable), Parent.Default, Variable)

If you will need to clear the inputs and reset to default, set the variable to Blank()

Best regards,

I think something is wrong, because when I choose the picture, the correct value stays there for a couple of seconds, then it resets to Blank by itself.
I think it happens because the default value well is blank, but to my knowledge, it shouldn't automatically update

EDIT: Solved it, I had a formula in OnVisible that reset that field. I deleted it and now it's working as intended

Hi @msabau ,

Please add a Label anywhere on the same screen as the pictures and set Text to the variable. Use double-slashes "//" to temporarily deactivate the Navigate function if there was, and check if the variable will automatically change after choosing a picture.

Best regards,
