i'm getting a "return not in function" error on the return for chkEach()
does anybody know the general cause of this error because it keeps coming up?
Thanks for yr time!
//TP
chkEach(FeildIDs,funct)
{
var arrFeilds = new Array();
arrFeilds=document.getElementById(FeildIDs);
var arrErr= new Array();
for(var i=0; i<arrFeilds.length; i++)
{
arrErr.push(funct(arrFeilds));
}
return arrErr;
}
Rest of code:
//TP
function chkboxRange(chkboxarray, min, minerror, max, maxerror)
{
/*
Creates Array
- var arrName = new Array()
arrName[0]="item1"
arrName[1]="item2"
arrName[2]="item3"
- var arrName=new Array("item1","item2","item3")
- var arrName = ["item1","item2","item3"]
*/
var arrSelect =[];
//Cycle thru checkbox array
//since first index=0, length is always 1 more than last index.
for(var i=0;i<chkboxarray.length;i++)
{
if(chkboxarray.checked)
{
//if checked, push id into Select array.
arrSelect.push(chkboxarray.id);
}
}
var arrError = new Array();
//if min exists & length is less than min, add minerror to arrError array.
if(min && arrSelect.length<min)
{
arrError.push(minerror);
}
//if max exists & length is less than max, add maxerror to arrError array.
if(max && arrSelect.length<max)
{
arrError.push(maxerror);
}
return arrError;
}

Regular Expression Key:
/ - pattern must begin and end with / in Javascript
Modifiers Before or after
g Do global pattern matching.
i Do case-insensitive pattern matching.
m* Treat the string as multiple lines.
s* Treat the string as a single line.
x* Ignore whitespace within a pattern.
* Modifiers that are not supported by Navigator 4.0x and Internet Explorer 4.0.
Examples
/JavaScript/i matches both "javascript" and "JavaScript"
Rule 2: | Seperates alternatives
Rule 4: Assertions
^ Matches at the beginning of the string.
$ Matches at the end of the string.
\b Matches a word boundary (between \w and \W), when not inside [].
\B Matches a non-word boundary.
Rule 5: Quantifiers
{m,n} Must occur at least m times, but not more than n times.
{n,} Must occur at least n times.
{n} Must occur exactly n times.
* Must occur 0 or more times (same as {0,}).
+ Must occur 1 or more times (same as {1,}).
? Must occur 0 or 1 time (same as {0,1}).
Rule 6: Special Characters
\n Linefeed
\r Carriage return
\t Tab
\v Vertical tab
\f Form-feed
\d A digit (same as [0-9])
\D A non-digit (same as [^0-9])
\w A word (alphanumeric) character (same as [a-zA-Z_0-9])
\W A non-word character (same as [^a-zA-Z_0-9])
\s A whitespace character (same as [ \t\v\n\r\f])
\S A non-whitespace character (same as [^ \t\v\n\r\f])
