Insert and update issue

Hi there, I have a system where I am adding product options to a product. I have an Insert and an Update on the same page (wanted this method as its easier for the client to navigate around). The Insert works fine... but then I have 2 issues....

(the results are displayed on the same page - which is what i want so that client can update them (they are just tick boxes and a delete record link).

on the very first Insert the page doesnt display the newly inserted record (i noticed in the URL the product ID is missing...so I have to use the browser back button to come out of that page then reenter and then it appears)...however when I go and insert a second, third, forth..record for that same product..it updates the display of the page and all is fine (so the problem is ONLY on the first record being inserted for that product).

my second issue is that the update record doesnt do anything on that page...so I am wondering how I can get the insert and update to both work nicely on the same page.

here is the file in question....

regard in advance Chris
