Edit Template with blank fields

I have a list of jobs using a datagrid. When the user clicks on the job
it brings up a seperate page with an edit template. If all the fields
are filled in then it lets me make changes. If one field is missing
like Date In: in doesn't update anything. It will just refresh the page
and not make any changes. I have allow null on for the fields in the
SQL database. Any help would be appreciated.

re: Edit Template with blank fields

I figured out the answer. It was my update query statement that had to
be changed.
