Field length problem!

[Simon Abolnar]

Hello!

When I add record in database everything works OK. When I modify data in database using
RS.Update
function everything works OK again when I use the same or less length field that it 
was before. (lets say "123" to "456" or "45" o "4")
The problem is when I use greater field length (my sql respond as error)
(lets say "123" to "4567")

What should I do to avoid this problem?

Thanks all!

Simon
