Excel Format

[lehainam]

Dear all,

I have a problem with format

In cell A1, I enter 'Happy birthday' I can see it.
In cell A2, I enter 13000000 I only #####.

I want to keep the with of this cell unchanged because if I change the width of this cell the other part of whole form is affected.

Could any one help me how to format A2 to see the whole number or what I enter. See the attchment

Thanks,

Nam
