I have used a list in a validation drop box, but the text size when veiwing
the list is very small. How do I increase the text size in the drop box?
Once
a item is selected off the list it is shown in the validation cell as per
the
cell format. I have tried to change the format in the list, but this
doesn't
change the viewed size of the validation cell drop box.
