Here's a test that passes in cgi.query_string
gives a cryptic strring as a return.
http://dev.mxconsulting.com/sergv2/testSTringUdf.cfm?object=true
Throws an error:
http://dev.mxconsulting.com/sergv2/testSTringUdf.cfm
Throws an error:
http://dev.mxconsulting.com/sergv2/testSTringUdf.cfm?o
If the string is less than 1 character long it throws an error.
I can only assume that something is crazy about the value being passed IN to the function.
This function appears to take items and shift the ascii character code value 3 to the left. I'm guessing that the ascii
character code in some cases is less than 3 causing some sort of end marker to be placed and thus befuddling your
"len( )".
I would do something like:
if(tempStr LT 4)
tempStr = tempStr + 254;
Then your values would "wrap" through the ascii code table.

What does this do for you?
<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);
}
strReturn = 'Too Short:' & newstr & ':end';
if (len(newstr)+1)
strReturn = left(newstr,len(newstr)-1);
}

Good question, but no, I have ran the output several times and checked
all values none are blank.

Is your input string empty?

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?

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);
}
