excel help please

Did you possibly drag them to hide them? If so, the unhide function won't work and you'll need to drag them back IYSWIM.

Is it possible it has been filtered to only show blank rows? Is there a small arrow at the top of the columns?

You have to highlight the rows/columns on either side of the hidden ones and then use the unhide function as you tried before

Thanks we can't highlight as they have gone - I tried and also its not filtered and its not neding to be dragged. someone has managed to fix it but we don't know how!

Thanks all anyways xx

So you have hidden column B then you highlight columnA&C & unhide.

is that what you mean.
