Hi,

This may be simple for some or most of you but it's doing my head in a bit.

II have created a sheet that gives time stages a points throughout a process, each individual cell add a number of mins from the next to form a trace.

I will only be interested in the values if I have entered a starting time but at the moment I have displayed every cell with a formula in it...I only want to have a cell display a time if I have entered a start time.

Question is how do I get the cells to remain blank until I enter the start time??

Any help would be great
