Drop down menu - then using the answer later

I am making an NPC Generator, I have sorted out lots of roll-tables but there is something I want to tidy up.

I have a drop-down-menu that asks the Island the NPC comes from and then gives information from the roll-table. I would like it to list the island I select somewhere else. Is there a way to do that?

So I have;

{{Home=[[1t[?{Island|Alaron|Moray|Snowdown|Oman|Sarifal}] }}  this works fine

I'd like to be able to have another box for

{{Island=*the selection made earlier*}}

I hope that makes sense. Thanks to anyone that can help!

D&D 5e OGL is that makes any difference.

You generally can reuse queries as long as they are identical; have you tried:

{{Island=?{Island|Alaron|Moray|Snowdown|Oman|Sarifal} }}

?{Island} will return the chosen value anywhere in the same macro, but it will not be usable afterward. I.e. it will not be usable in another macro you run at a different time.

Sounds perfect. Thank you!

edit: tested and it does what I needed, thanks again!
