Global variable is not passing to other pages

Hi,

I have been working on creating my own app and I'm trying to pass a variable from one page to another (not from one screen to another) and for some reason it's not populating even though it says "Global Variables are defined across the app and can be referenced by other screens. Maybe I'm miss interpreting it but regardless I need to pass a variable from one page to another. I have set the variable:

Set(selected, Associated.Selected.'Name'); # This is selected from a table within the page
selected; # This is checking that the variable is holding the information on row select, it does hold the value check video
Navigate('Directory', ScreenTransition.None, selected) # I get issues with this because it says the 'Directory' (The other page) is not a control or a screen for this page of the app
 
I also attempted it with a button and it still refused to pass the variable to the other page:
Set(selected, Associated.Selected.'Name');
selected;
Navigate(ToBOM, ScreenTransition.None, {selected : Associated.Selected.'Name'}) # ToBOM is the button (or "Control") that I was attempting to use
 
I'm really at a loss here because it should be defined across the app not just across one page of the app. SOS

Global variable is not passing to other pages

Hi @SW-23041510-0,

There are a number of things you are duplicating here that may be the cause of your issue. Firstly, let's keep it simple - assuming Associated is the name of the Gallery (galAssociated would be a better naming protocol), you also need to stay away from selected as it is a Reserved Word in Power Apps.

Set( varSelected, Associated.Selected.'Name' ); Navigate( 'Directory', ScreenTransition.None )

If the 'Name' (not a good field title) field in the record selected in the Associated Gallery contained the relevant value, then this certainly will be available as varSelected on the second screen.

Looking at your present code, when you did this

Navigate( ToBOM, ScreenTransition.None, {selected : Associated.Selected.'Name'} )

you actually attempted to set a second Variable (a Context Variable applicable only to the second sereen) with the same name and taking precedent over the Global Variable you might have set earlier.

I am not sure what effect this had,
Navigate('Directory', ScreenTransition.None, selected)

but is not valid syntx that will assist anything.

So please try the process at the top of the post - it should work for you.

@SW-23041510-0,

I would like to understand, Global Variable means global across the screens in the app no need to pass from the one screen to another screen.
