How to reference variables from what was fetched from Sharepoint List

Hello,

Sorry for the newbie question...

I have a gallery that correctly pulls records that contain fields A, B, C, and D from my Sharepoint list called Equipment. PowerApps auto-built an item detail screen that is forms based and sticks the variables in it in a form. When I click on the gallery item the command Select(Parent) takes me to the detail screen.

Is there another way that I can directly reference the values in fields that were pulled the Sharepoint list for the current record? I don't want to use a form, but would very much like to be able to test and compare the variables on this new screen.

...and can someone give me a simple explanation of what Select(Parent) does? I've tried to understand what this does, but I don't get it. I just want to be able to manipulate the fields in what ever record is selected from my gallery on a new page.

The easiest way to reference a gallery record throughout your app is to put it into a GLOBAL variable, ie

// OnSelect of your gallery Set(vCurrentRecord, ThisItem); // If you also wish to Navigate to another screen after the above, add Navigate(Screen2, ScreenTransition.CoverRight) // use your screen name and preferred transition method

You can then access 'vCurrentRecord' anywhere, eg in a Form, insert a Label and use vCurrentRecord.Column1, etc

Select(Parent) is generally used when Galleries are created and you will see then on the Right Chevron '>'. This just means "select this gallery item' or 'this is the selected gallery item', etc. If you were to add the above code to your gallery OnSelect then Select(Parent) would also set vCurrentRecord to ThisItem. You don't really need this code if your gallery has OnSelect code as it's just doubling up.

So then I can reference each field in the record by ThisItem.A, ThisItem.B, etc?

You would use vCurrentRecord.A, vCurrentRecord.B, etc

ThisItem is reserved for Forms and Galleries so wouldn't work outside of these.

Hmmm.... vCurrentRecord.Equipment isn't valid. This identifier is not valid. Equipment is the first field in my record.

Cool. It's working now. My new code just needed to be acknowledged everywhere. It seems sometimes that PA is slow to code changes like this.

Thanks for your help. I'm over this hump and can move ahead with this app!
