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>
