If I use this formula:
I get this result when {Body: Left Foot} is NOT empty, WHICH IS WHAT I WANT:
But when {Body: Left Foot} is EMPTY, I get this result that has an extra COMMA:
When I take out the comma in the second IF statement, then there's no commas at all whether or not {Body: Left Foot} is empty.
So... what's up with that? Shouldn't it ONLY put the comma IF there's content in {Body: Left Foot}?
