Hi JBeaucaire,
Thank you so much for your reply,
I still need more info, my specific question is as follow:
when i make a worksheet, i need to skip some specific cells as when i move
across the cells using "enter" or "Arrow" bottons, the specified cell should
be skiped as constant value, in another word, i need to skip it when moving
across the cells
