Error Syntax Template (which line!?!)

[Anonymous]

If I am copying and pasting in my local template design and Marketo throws the "Validation Error" how the !@*& am I supposed to know what line that error is on? This is driving me insane trying to debug this thing.

Whats even more insane is I will comment out a line I think might be throwing the flag, and the validation clears. Then I will uncomment, and get the error. Then I will comment out again that *same* line and get the error again whereas it cleared the first time!
