You are creating a link to screen button, correct? The problem is you are setting up the layout for each item in the home tab. Layouts are tied to sheets, so the layouts for each item are going to be the same, so a link to screen for one podcast is going to be the same link to screen for another podcast. This gets really complicated since you have podcasts on separate sheets instead of joined in one sheet. If they were joined together, then you could use relations to link the podcast to the list of episodes that are related to that podcast, but I suppose that’s a problem because you are using IMPORTFEED to get data. The link to screen button is just pointing to the last sheet you specified for that button.
There are a lot of ways to fix this:
One would be to use a query to join all the sheets together. I would make sure to add a column in each sheet first that uses a formula to fill in a Podcast name for each row that’s filled. Once you have everything in one sheet, then you can set up a relation and use the List Relation component to link to only the matching episodes for each podcast artist.
Another world be to split up your home sheet into separate sheets for each artist. The using your home sheet as a placeholder, create an inline list that points to each artist sheet, so it will appear like one list, but will actually be a several lists. Then you can design each artists page individually with a link to screen listen button that points to the correct sheet.
Another option is to set up a relation column to each episodes sheet, then set up a List Relation component for each relation. Only the List Relation component with a value that matches the value in the sheet with matching episodes should show.
There’s probably lots of other ways to do this this, but here’s a few. My vote would be the first option, since it makes things easier when similar data is together in one sheet.
