Hi Alex Garland,
Syntax : ${MapName[modelVar.map_key].value}
Try this : ${entry1[transfer_target.key]}

Possible reasons of error
->Make sure you have imported liferay-ui taglib
->I hope the code is proper and no errors. I see that there is no semi colon after map and list declaration and initialization.
->Either escape or use single quotes when you are getting the value from map.
->Try to use toString after getting the value.
I have refactored your code so as to incorporate the comments I wrote above, but havent tested. See if it is working for you
