Queries :: Passing Column Name Parameter To Query

SUMMARY:
In Access 2007, can I pass a Column Name as a parameter from a Combo Box in a form?

DETAILS:
I would like to use a String value from a Combo Box as a parameter in a Inner Join query:
...
WHERE (((AAA.HSC) Like Forms!My_Form!My_TextBox)
AND((CCC.Forms!My_Form!My_ComboBox)="X"))

Where "CCC is a Table from my Join Query

I'm able to run the code above without generating any errors. However, instead of the query accepting the value from the Combo Box, it opens a pop up asking for the value of "CCC.Forms!My_Form!My_ComboBox", not once, but twice! After it finally runs, the result set is empty when it should not be. I also find it strange that it is asking for the combo box value with the Table name appended to the front.
