Ok, I give up UDF error

[Mark W. Breneman]

This seems so simple. All I want to do is to trim the last char from the
return string.  I keep getting this error "Parameter 2 of function Left
which is now -1 must be a positive integer"



If I hard code a value in the UDF works with out a problem.  But when I
put in the len(newstr)-1  into the "left" function it seems to evaluate
to 0.

Can anyone help me out?

<cfscript>

function qdecode(urlvars){

            var tempurlvars = URLDecode(urlvars);

            var strlen = len(tempurlvars);

            var tempstr = "";

            var i = 1;

            var newstr = "";

            for(i=1;i lte strlen;i=i+1) {

                        tempstr = Asc(Mid(tempurlvars, i, 1));         

                        newstr = newstr & Chr(tempstr - 3);

            }

            return left(newstr,len(newstr)-1);

}

</cfscript>
