I do not see any element in that code that has an "id" attribute of "PermissionID". So when you call that element in your code you are trying to access an object that is null.

Thanks for the quick reply. Per your instructions I added the ID field. and I still get the same error.


<input type="hidden" name="PermissionID" id="PermissionID" value="1" />

However I am able to get it now by

d.getElementById('PermissionID').value


Why is that >???????


f.PermissionID.value = 1 should have worked.

[hsriat]

I'm not sure why is this not working, but

Try with

f = d.forms['ShareOptionsForm']
OR
d.forms['ShareOptionsForm'].PermissionID.value = 1

If first one works, this means we may not declare form as variable like
f = d.ShareOptionsForm

If seconds works, this means we may not declare any variable to save form in it.

If none works, there's some problem with the other part of the code.
