Am desigining a webpage, and part of the requirements is to have a 9 digit tax file number input box, laid out so the number can be broken up into 3 sections of 3 digits.

So I figure the easiest way to do this for the user and myself is to make 3 textfields.

<input type="text" name="tfTFN1" size="1" MAXLENGTH="3" onChange="tfnMoveNext2()" />
<input type="text" name="tfTFN2" size="1" MAXLENGTH="3" onChange="tfnMoveNext3()" />
<input type="text" name="tfTFN3" size="1" MAXLENGTH="3" /></td>

Now to make this even more user-friendly, I've been trying to write a function that jumps to the next text box, like on most unlock keycodes on a lot of software.

function tfnMoveNext2()
{
	sTFN1 = document.inputForm.tfTFN1.value
	if(sTFN1.length == 3)
	{
		document.inputForm.tfTFN2.focus()
	}
}

function tfnMoveNext3()
{
	sTFN2 = document.inputForm.tfTFN2.value
	if(sTFN2.length == 3)
	{
		document.inputForm.tfTFN3.focus()
	}
}

Alas, my function does not work. Can anyone see an error in my code? Am I looking in the wrong direction with this thing?

i'm not very good with js, but i know some basincs

are you telling it to focus on whatever your text field is called?

Yes, I'm telling to focus on the next next field after the one in focus is filled.
