macro to blank combo box selection

I have 63 combo boxes on a worksheet. Each one has a name associated with it ("Pick1" ... thru .... "Pick63"). Each combo box has 3 drop down lines where the #1 selection of each is a blank selection.
I want to write a macro that will in effect select the "blank" (#1) selection of each combo box. I am not familiar with code regarding combo boxes.
Thanks in advance for your help!

Is your combobox directly in the worksheet or you have it in a Form?
If you indeed have it in the worksheet, I would suggest that you configure the cell to manage a list.
To do so, select a cell, then in the menu select Data -> Validation. In there, select the "List" Option. As source, you could use a range of cells (each cell value will be an option in the drop box).
In this approach, if you want all 63 to be "Blank", you just need to write a macro with Range("A1:A63").Clearcontents and they will all be blank.(concidering your drop boxes are in cell A1 to A63) .

Hope it helps.

Thanks Wizz,
The combo boxes are spread out on the worksheet and there are items that I do not want to clear.
I did not have the cell managing a list but the [Range("A1").clearcontents"]command does empty the cell like I want, therefore I will be able to use this to manage all of the combo boxes.
Many thanks for your help!
