Hi there, Bit of a weird one. Delivered something to a customer last night, went home, came in this morning to find the customer was having problems. I looked at the error: Error Type: TALESError Error Value: exceptions.NameError on global name '_' is not defined in "standard:'here/xxx'", at line xx, column x ...which seemed pretty obvious. I went to the bindings tab of the python script in question and sure enough, the namespace box was empty. Now, the thing is, I _know_ this was bound when I left last night. I checked to see if anyone had edited anything, and nothing had been changed since I left last night, and there were no new transactions in the undo log. So, basically, I'm rather miffed and my confidence is a little shaken. What on earth could have happened here? cheers, Chris
