Hi,

I have a worksheet in which I'd like the user to only be able to enter
data
into certain cells if the A cell in that row contains a date.

Where the A cell in the row is empty, the user should not be able to enter
any data into these particular cells, although they will be able to enter
data into other cells in the row.

I thought I should be able to use custom data validation to do this,
however I'm a bit stuck on the formula to use.
