Form Validation Won't Work In FF

[T0PS3O]

Can someone please have a look at this code for me please? This works just fine in IE but not in FF. Can someone guide me in the right direction re: which part is the culprit please?

<SCRIPT LANGUAGE="JAVASCRIPT">
<!--
function CheckForm() {
var Result;
Result = "";
//Result = Result + chkemail(document.theForm.Email.value, ", Email");
//Result = Result + checkDropDown("Property", ", Property");

Result = Result + chkLength(document.theForm.ContactName.value, ", Contact Name");
Result = Result + chkLength(document.theForm.CompanyName.value, ", Company Name");
Result = Result + chkemail(document.theForm.EmailAddress.value, ", Email Address");
Result = Result + chkLength(document.theForm.Password.value, ", Password");
Result = Result + chkLength(document.theForm.ConfirmPassword.value, ", Confirm Password");

//Result = Result + chkLength(document.theForm.YourName.value, ", Your Name");
//Result = Result + chkLength(document.theForm.ContactsSurname.value, ", Surname");
//Result = Result + checkDropDown("Sector", ", Sector");
//Result = Result + checkDropDown("country", ", Country");

if (Result.length > 0) {
document.all['Val'].innerHTML = "Complete the fields: " + Result.substr(1);
return false;
}
else
{
return true;
}
}
//-->
</SCRIPT>
<SCRIPT LANGUAGE="JAVASCRIPT">
<!--
function chkLength(str, response)
{
strReturn = "";
if (str.length < 1) {
strReturn = response;
}
return (strReturn);
}

function checkDropDown(dropDownName, response)
{
strReturn = "";
if (document.theForm[dropDownName].selectedIndex == 0) {
strReturn = response;
}
return (strReturn);
}

function chkemail(str, response) {
strReturn = "";
if (str.length > 0) {
i = str.indexOf("@");
j = str.indexOf(".",i);
k = str.indexOf(",");
kk = str.indexOf(" ");
jj = str.lastIndexOf(".")+1;
len = str.length;
if (!((i > 0) && ( j > (i + 1)) && (k == -1) && (kk == -1) && (len - jj >= 2) && (len - jj <= 3))) {
strReturn = response;
} else {
if (str.length < 1) {
strReturn = response;
}
}
} else {
strReturn = response;
}
return (strReturn);
}

//-->
</SCRIPT>

Form element example:

<form action="new_go.asp" method="post" name="theForm" onSubmit="Javascript:return(CheckForm());" ID="Form2"><input class=x id=Text1 type=text size=60 name=EmailAddress>
<input class=Button id="Submit2" type=submit value=Submit name=Submit1></form>

Validation works great in IE, not in FF (redirects to homepage, strange!).

Thank you!

My web developer toolbar says "Error: document.all has no properties". Google searches seem to suggest innerHTML is not part of the DOM (whatever that may mean) so FF doesn't support it. Can this be true? Ideally I'd rewrite the whole validation to server side but I'll have to give fixing this a try first...

This is the line.

document.all['Val'].innerHTML = "Required fields: " + Result.substr(1);
