The easiest way is to give the list a name on the other sheet
insert_name_define. then in your cell validation choose list and type
the name of this list
It will still work, but you will be left with blank values as long a
the merging is in the same column. If it is merged over 2 columns i
will not work. Merging cells is often a bad idea in excel, it can caus
lots of problems.
