Hello pals!

Well i am looking for a solution of a problem i am facing currently.

I got a excel table say A1, B1, C1.....................F1 - (cells)

Now after i enter data in cell A1, i use tab to move to next cell that
is B1, but i want data to be compulsorily input in B1 - if i move or
press tab accidentally to move further, that is to C1, i want a pop up
message to appear, "you can't proceed, unless u enter data in B1"

Do anybody can help me out in this, would be greatful if you do.

Still scratching my brains ***@@@###$$$*******

Thanks,
Cheers
Gladson.
