Thank you for your reply!
Yes, you are defo on the right track.

'Then whenever tab1 loses focus or gains focus, do an update/select respectivley'
This is where I get lost - Hangon, I think I have got it. When a user clicks on the a tab, I pass a paremeter in the querystring (ie, tab2.php&currenttab=1). Once submited, I have a switch statement,

case(currenttab=1)
'do update
case(currenttab=2)
'do update
end case

` build html for new tab...

Is this what you mean? I think that will work.

Thanks,

Paul
