AppleScript 'choose from list' - I'm having trouble with Multiple Selections

Solution 1:

At the point where you are having a problem, result is a list. Try looping through the items in the list.

set answer to choose from list {¬
    "App1", ¬
    "App2", ¬
    "App3"} ¬
    with prompt "What would you like to do?" with multiple selections allowed and empty selection allowed
if answer is not false then
    repeat with appitem in answer
        activate application appitem
    end repeat
end if
