Does limesurvey support STR_PAD_LEFT? I am using: str_pad(storeNum, 5, '0', STR_PAD_LEFT) but LS wont recognize pad left. It gives me a "undefined variable" error.

Thanks.

here is the list of support EM functions. Is this something you are looking for?

I dont think so. I was working off of this in an equation field. Basically I have a place where someone enters their store number which can be at max 5 numbers. But all store numbers have leading 0. So if someone enters in store 20, their real store number is 00020. To make sure that the store number shows correctly even when people dont enter the leading zero I made the above code in a hidden equation field. So LS has support for str_pad and it works using just str_pad, it just pads with zeros the wrong way (default is right) but I need it to pad left.

I think EM don't have the fourth parameter.

Then need another system

Something like this maybe:

Thanks, that works out great.
