Thanks, that will do the trick. It took me a minute or two (very tired) to understand what you are doing...

store the record number
go top if the same we are at the top
go bottom if the same we are at the bottom
go back to the record number we were originaly on.

Simple... are there any cavets with this code?


Thanks
