Hi, I am hoping that someone can help me with Tabbing options in Excel when I have created an ActiveX Combo Box. I am not a developer, So "basic" language is required

The worksheet has only the 1 Combobox per row, the user needs to beable to tab from A3 to B3 to C3, etc. However in C3 I need the Tab to activate the ActiveX Combobox not the field behind it and then once the value has been set in the ActiveX combo I need the Tab to take the user to D3. I do hope I have given enough information.....
