Here's an example for you: <dtml-call expr="REQUEST.set('tempvalue','000001.abc001')"> <dtml-var expr="_.hex(_.string.atoi(REQUEST.tempvalue[-3:],16)+1)"> Have a read of the Python docs on string.atoi and 'slices' (the [-3:] bit) in a string context. They're your best friends in this case. Cheers, Jules
