Hi @vshah2 ,
Something like this
Filter( YourOtherCollection, ID=YourGalleryName.Selected.ID, YourOtherColumn )
or
Filter( YourOtherCollection, ID=YourGalleryName.Selected.ID ).YourOtherColumn

Hi @vshah2 ,

I agree with most of @WarrenBelz 's thought. But I need to correct you a little. Filter function could not get field's value(formula1).

In formula2, you will get a table, not a value neither.

Do you want to filter another collection based on the selected ID in the gallery and get one column value from the filtered collection?

If so, I suggest you try LookUp function, which could get the filtered item's field value.

Try this:

LookUp( YourOtherCollection, ID=YourGalleryName.Selected.ID, YourOtherColumn )

or

LookUp( YourOtherCollection, ID=YourGalleryName.Selected.ID ).YourOtherColumn

Please refer this doc to see the differences between filter function and lookup function:
