Error in page with Chrome but not with Firefox or IE

[eluser]vincej[/eluser]
the reason why $tel_customerid was to cater for the event that the user wanted to use backspace and refresh that page.

yes, I could have used an additional query but in my estimation it was more appropriate to temporarily use a session to server a back space event.

I don't like using additional queries to get data that I already have.

thanks
