DIV hide failure

[Dave Hannum]

OK - this is stupid I know, but why does this not hide the div when the
conditional is not met?  If acctForm.MemID length is 0, it displays the
div - but if the user tries again, and acctForm.MemID is not zero, it does
not turn around and hide it.  If someone can help, I'd be appreciative.  No
errors are thrown.

onload = setscreen;
function setscreen() {
 if(document.all) {
  document.all.a.style.visibility = 'hidden';
 } else if(document.getElementByID) {
  document.getElementByID("a").visibility = 'hidden';
 } else {
  document.layers["a"].visibility = 'hidden';
 }
}
function acctNo() {
 setscreen()
 if(document.acctForm.MemID.value.length == 0) {
  if(document.all) {
   document.all.a.style.visibility = 'visible';
  } else if(document.getElementByID) {
   document.getElementByID("a").visibility = 'visible';
  } else {
   document.layers["a"].visibility = 'visible';
  }
 }
}

OK - I said it was stupid.  It works in IE (must have been a caching issue) however, it does not work in Firefox.  Any suggestions?  Nothing ever displays.

I changed the order it looks for the layer/getElementByID/all and it works.  Thanks Dave <grin>
