Combo box with list box help

Hi Guys,

I am using Macintosh OS X and Microsoft word for Mac 2011.

I am having more than 10 macros. I like to run the macro by using Combo boxes and list boxes.

For example:
Combo box 1 with 3 list items
Combo box 2 with 5 list items
Combo box 3 with 4 list items

I am new to the Mac World and less knowledge in VBA.

Can any one guide me, how create a combo boxes and list boxes. Or is there any pre-defined code, which I can modify to my need.

Thanks in advance
Rakesh
