"fieldname" has no meaning in html, 
do you mean field like in 
<input type='text' name ='a' id='b'>?

getElementById() needs the id of a tag, not the name.

Only clumsy IE seems to allow the name if an id is absent.
[better forget about that and never code for IE alone again.]

Use correct code and do not set your trust on the silly IE shortcuts:

document.getElementById(myId)

============

Understand that a name can be given to multiple tags, so ths will return 
an array, and you would have to specify the member:

document.getElementsByName(myName)[3]

[This does not exist: getElementByName]
