In my spread sheet the Used columns are from 'A' to 'T'.
Out of those columns few columns should not have blank cells.
For Eg: A, B, C, D, H, I, K, N coulmns should not have blank cells.
If there is any blank cell in those columns for eg in 'A' column then, I should get msg box saying 'There are blank cells in 'A' column'
Can any body help me.
Thank You
