How can I link a Macro userform to a specific cell?

So I Know how to Make A user Form (drop down)Combo Box. As well, I linked it To a Column of Company Names on worksheet Number 3.

Now I would like to recall it to Worksheet number 1, in a specific cell ("B8").

I would also, like to link a second (drop down)Combo box to another cell in sheet 1 ("B9"). Where as when I chose the customer from the list, It triggers an autofill in three other Cells ("B10,B14,B15). The source of their autofill would be from sheet 3.

Reason I need two sources is that the companies i deal with often have more than one supervisor with different phone numbers etc.

Is this even possible?
Any Help or direction would be greatly appreciated.
Thank you for your time.

Thanks Jerry Ill give it whirl
