a = int(param) also if that is the actual code you will want to either make line 2: a = a + 1 or the last line: return b Code inside python scripts is "python" so you can find the answers to these types of questions by either purchasing a python book or reading the python references at www.python.org.

It has only one parameter and all it does is add 1 to the param value: a = param b = a + 1 return (a) The problem is (I guess) that 'param' isnt a Int value, how can I "say" to zope that it is? Thanks for the help!!
