Validate field by field problem

[necta]

I have this validate field by field problem. I used the method below but the error "textfields.length not an object" appeared.I tried on marks.length, it also gave the same error.What have I done wrong? I used on blur to validate each field. The 'elements.length' work in checkbox but not here.

Thank you

<!--
function numValidate(mrk)
{
var mrk;

for (i = 0; i < mrk.textfields.length; i++)
{
// check to see if the number field is blank
if (mrk.textfields.value == "")
{
alert("Please enter a number.");
mrk.textfields.focus();
return (false);
}
}
}

<
<input type="text" name="marks<%=subjNo%>" id="marks<%=subjNo%>" type="text" size="4" value="<%=subjNo%>" maxlength="3" onblur="return numValidate(this)">

sRS.moveNext
Loop

Have you tried testing

mrk.length

and

mrk[i].value

?????

I notice your function numValidate takes a parameter (mrk), however just inside the function your are declaring a variable of the same name which is probably over-riding it.

Doesn't look like you need the variable inside the function.
