Function sorks with one parm, fails with two.

Function sorks with one parm, fails with two.

I am trying to write a function to calculate a sales total, based on radio button choices that I can use in multiple applicatiions. I've spent a lot of time looking at this. Either I am missing something really obvious, or perhaps I am going about this all wrong.

The total is changed correctly when the function just has one parameter (type=string). I need a total of 5 or more. When I add the second one, the ZOHO form will either hang or I get a zero result.

Could this be a bug?
