It looks like you're using join incorrectly in your data collection loop. The join function uses the first item in its argument list as a separator which is placed between all the other items in the list. It looks like you're using it as a concatenator, which it will fail miserably at (at least the way you use it).
For example: print join('a','b') will print the letter b on your console, and print join('a','b','c') will print "bac". Normally, you'd use it like print join(", ", 'a', 'b','c') to get a nicely formatted list: "a, b, c".
So you can change:
or you can build an array to hold your interfaces, and join them at the end.
Update: Fixed example (to "bac") ... thanks for the catch johngg!
