OK, try this...
When you first hit this page, it will have todays date filled in, with
Material and Weight blank.
When you click the submit button it checks to see if weight is > 1200. If
it is, it repaints the form with the same material, the next date and the
remaining weight.
If the weight is less than 1201 it repaints itself with material blanked
out, and the day set back to today.
You still have to handle error checking, the process of creating the order,
and determining the value of Today. If you don't use a day counter for
Day, you may have to do something besides adding 1 to Day to get NextDay.
Note this program calls itself when the submit button is hit. You will
need a link on the page to break out of the loop. To start a cycle of
adding entries, just hit the page, it will initialize itself.
