Question : Create a bound dropdown combo box with autocomplete

I have a combo box which i threw together and I designated the control soure to my bound form but when i use the mouse wheel to sort throught the records it replaces the data in my fields to numbers - not sure where they are comming from.

I am gonna of course replace the data back to its original state and then follow your directions on creating a dropdown box that meets the following criteria:

1) Must contain auto-complete functionality
2) once a record is chosen in drop down - the corresponding info in the bound tables must refelct the change.
3) Must not be editable or change the field data in the dropdown in any way.

Thanks in advance to anyone who can help explain in step by step process of how to address this.

Control Source is the filed you want to store the data in.
Row Source is where you want to click on the elipse and create the query.
