Using Set to define a variable from multiple locations

Hi all,

I am trying to set a record to a variable from multiple controls and receiving an incompatibility error, even though the two definitions are both records.

I am building an app that allows users to search a collection to find a needed document, select it, and bring it up in the PDF viewer. When a user selects an item from the gallery, it sets varItem as searchGallery.Selected, then navigates to the search result screen. OnVisible, the search result screen runs a PowerAutomate flow to retrieve the PDF data of the selected item using varItem.

Search Result Screen

Selected Item screen

My issue is that I don't simply have one gallery that users can select to set varItem, but 2. When a user selects the "Show Related" button on the search result screen, it brings up a gallery of related documents they can also launch. This has the same syntax as the original gallery, Set(varItem, searchGallery.Selected), however it produces an error saying my variable types are mismatched:

Related Documents Gallery

I know that the only two definitions of varItem define it as a record. Is there a way to define a variable from multiple locations or another workaround? Any guidance would be appreciated.

Thanks!

The schema of the records is what is important - not just that they are records. PowerApps will throw an incompatible type error if you try to set a variable to one record with a specific schema, and then to another record that has a different schema.

So, no, you cannot do that in this case.

You can alter the schema with datashaping functions in PowerApps on your Gallery so that the gallery columns/schema are identical in all the places you want to set a variable. Then you will have no issues with it.

I hope this is helpful for you.

Yes, you are exactly right.
Instead of having two unique galleries, I copied the original and reused it for the second one. This aligned all of the data points within the record. I had no idea that using Set wrote columns from the datacard into the record. I also realized that in one gallery I had Set(varItem, ThisItem) and Set(varItem, searchGallery.Selected) in the other, which also gave me the incompatibility error. After aligning the two galleries and Sets, it is working as intended.

Thanks!
