How to take value of variable out of a 'for' loop

Hi everyone,

I'm trying to figure out how to take a value of a variable outside of a 'for' loop when it's declared inside of the loop. I know this could be easily done by doing everything inside the curlies as the value of a variable does not exist outside of it, but it can't be avoided when trying to get a joined record field in a transaction column, thus, a nested loop.

Say for example you have a transaction record, with a list/record column field 'joinedrecord_name' where a joined record is selected (id shows in the field). Then, you have another column textfield in the transaction column called "joinedrecord_text" where I want to populate the value from one of joinedrecord_name's item list field. Let's call this field "text_field_in_joined_record".
