I have a spread sheet with various columns in use. I cut and pasted a formula from a different location into all of the cells of one column. The formula calculates the correct answer however the 4 lines that make up the cell (so to speak) vanish.

How do I get them back? I tried changing the size of the cell but the lines do not come back. Hard to explain without seeing so I hope its clear.

Any help would be appreciated. Thanks Peter
