RE: Ok, I give up UDF error

[Mark A. Kruger - CFG]

If the variable newstr is only 1 char (or a zero length string) - this is the error you will get. Output the value of
"len(newstr) and see what you get.

  Subject: Ok, I give up UDF error

  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>
