Having it said it seems obvious, I now have a second problem. I managed to apply the formatting to the required rows, but it seems to disappear...
Basically, I have a list (using the List option) of names and addresses in columns. I want to highlight the entire row if "Y" is added to the first column. I therefore sorted the list by "Y" (ie selecting sort ascending from the 1st column), which brought all the entries with "Y" in the first column to the top.
I then did exactly what you told me in order to make all the rows yellow (if "Y" is in comlumn 1), which worked. I filled the formatting down through all the relevant entries. All fine so far.
I then re-sorted the entries alphabetically (ie sort ascending in column 3) and the formatting disappeared. All the "Y"'s were still in the correct rows in column 1, but no yellow anywhere.
I re-sort using column 1 (bringing all the "y"'s to the top) and the formatting reappears. Back to alphabetical and it disappears again. I tried restarting Excel, no change. Is this a bug, or am I not doing something right??
Many thanks in advcance!!
