Hi @BCBuizer ,
Thank you for your reply.
Unfortunately lookup columns are not an option in this case, as this SP list already has the maximum number of lookup column associations compatible with Power Apps. I am not familiar with foreign keys- is there a reference with detailed instructions that you can point me to for how to set these up in a SharePoint List?
It is possible to set up hyperlinks to refer to items in other SP lists- we have this relationship established. The benefit of such a relationship is that it is possible to have a definition for each category there in the list, which is the reason a hyperlink column was used (in the absence of available lookup columns), rather than a choice column. The lists are shown below, along with the problem that I am having with the URL showing in the Power App rather than the list item name/text title for the URL.
This is part of the Parent List used for the PowerApp, with the Category hyperlink type column (note, within the Category column, the item name/text title for the URL is displayed rather than the URL):

This is the LB_Category List that the hyperlink type Category Column in the above list references:

And here is how the Category column data displays in my Power App (where the Default property is set to ThisItem.Category). I want it to show the Category name (1, 2 or 3) rather than the URL:

Any other suggestions for how to get the Power App to show the item name/text title for the URL in the Category List, rather than the URL would be greatly appreciated.
Thank you,
Nic
