[ic] Form field checking.... almost got it

[interchange-users@icdevgroup.org (DB)]

IC 4.8.6 using foundation. I have a form and want a few of the fields to 
be required. I do have this working, but if one of the required fields 
is left blank and one submits the form, you're presented with a blank 
form and must re-enter everything. Obviously I'd like the completed 
fields' contents to be retained.

Here's how my form checks the fields:

[set Check_form]
&success=feedback2
&fail=@@MV_PAGE@@
email=required
Model=required
Type=required
&fatal=1
test_last=required
[/set]

Can anyone provide hints?
