Hi,
You can do it by using dynamic named range. First define a new named range:
=OFFSET(Sheet1!$A$1,,,COUNTA(Sheet1!$A:$A),1)
and give it a name, let's say "list"
The above formula works fine if your list starts from Sheet1!A1 and has no blank cells in it (and nothing else in Sheet1!A:A under the list itself).
Secondly use the named range "list" in your drop down box. You can use it in Data Validation -> List or in Form Control -> Combo Box.
To use it in Data Validation, select a cell (or cells) you want to appy it to. Select Data -> Validation, change Data Validation criteria to List and in Source type "=list" and press OK.
In Form Cotrols Combo Box, first insert a Combo Box. The right click it and choose Format Cotrol. In Cotrol tab, type "list" in Input Range and press OK.
Hope this helps.
