Problem with an update page.

Question

I have a problem with an update page on my website
Here's how it work
values are defualted in from the advert table  - this works fine
I should then be able to change the fields and click on the update button
This works fine but ONLY when the O_year field is populated. 
There doesn't seem to be anything special about the O_year field
I thought spry text validation would of been causing the issues, but I removed them and have the same problem.
For some reason the POST_MMupdate value is not being set to 'form4', which it is doing if O_year is set.
Please can someone have a look at this, code,
Also, is there a way of 'stepping through' dreamweaver code to debug it?
Thanks

Answer 1

Please note,
Removing I investigated spry a little more, in the end I settled for removing spry altogether,
Maybe it was because the text field in a $GET (for the default) AND a $PUT (for the update)
