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[i]));

}

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[i].checked)

{

//if checked, push id into Select array.

arrSelect.push(chkboxarray[i].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;

}

/*

This function checks whether the passed parameter is null or blank.

In this we pass the value of the fields as a parameter.

If the str is blank or null, it will return true and otherwise false.

function isEmpty(feild)

{

//var str1=trim(str);

var str= feild.value;

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])

Missing keyword function.

function chkEach(FeildIDs,funct)
