"document.[formname].submit()" not working?

[wxdqz]

Hi- I have a simple, yet frustrating problem.
About a year ago or so, I created a simple page
using a form and links that submit the page.
Additionally, I have functions on it that fill some
input fields with values.

Now none of them are working anymore:
- the request "document.formname.submit();"
generates the error "Object doesn't support
function or method".
- the "document.formname.fieldname.value= 'xxx';"
generates the error "Is NULL or not an object".

I am sure it's something really simple and I am
just too blind to find it (overworked! ) but...
yea- it's discouraging.

Any suggestions?

Thanks!
