Hi folks, I'm trying to make a function be called from the onBlur of a text field, I had it working on another html file but I can't make it work in this script and I can't find out why...

Any help would be great.

Code welcome.

My script is attached bellow.

It IS working but:

line 30:  if (vercpf(document.frmcpf.cpf.value))

is throwing an exception:

document.frmcpf.cpf is null or not an object

Firefox Error Console says 'document.frmcpf.cpf' is not defined after 'onblur'.  The name of your form is 'form1'.  Is it supposed to be something else?  It works if you name your form 'frmcpf'.
