How to display two fields using join

Question

I have two questions in a repeat: Species and PercentCover Because these are in the repeat, I am using the join to create a running list of the species entered in the repeat. I have been successful at doing 1 field using join('
', ${Species}) outside of the repeat, but I'd also like to display the Percent Cover as well something like this join('
', ${Species},' - ',${PercentCover}) I know this doesn't work. I tried the concat outside of the repeat and it too works, but only for the current repeat and doesn't keep a running list like join does. If anyone can help out that would be awesome.

You need to concat() the two fields inside the repeat. Then display outside.
