Just can't get my head around this prob at all.

In cell C2, a drop-down list gives 5 options to select from :
"1"-"2"-"3"-"4"-"5"

In cell D2 I'm trying to create drop-down lists for each selected
option in C2.

i.e. If "1" is selected from the drop-down list in cell C2, a drop
down list of half a dozen options would be available in cell D2.

If "2" is selected from the drop-down list in cell C2, a drop down
list of a different half a dozen options would be available in cell
D2.

The same would apply for all the other selections.

Does anyone know how I could get this function operating? Would be
very obliged for some help

Thanks in advance.
