Building a Colouring Book Need Help


I really need some help, please.

I am trying to build a Colouring book for my community so the kids can paint the drawings we have, I have most of it done but I have a problem with one part.

I have set up a list view with Images from Airtable and it works ok but now comes the very hard part for me.

I want to take the users selection from the list, and then I need to add the correct download link from Spreadsheet2 and send it to my Canvas on Screen 1.

This is as far as I got before I got so confused I did not know what I was doing.

How do I get the selection from the list then send a download link from the second spreadsheet to the Canvas on the Scrren1?

Also, I am unable to copy my Screen1 in any way I get a server error if I try and copy any page.

Any help is helping me work out how to do this would be amazing as I am very very confused right now and do not know how to do this.

Screenshots of Blocks would be very useful Please.

Thank you
