VBA to Oracle replace routine issue

Experts,

I have a Excel VBA code that uploads data into a oracle table.  I want to pass a variable so it can do a find and replace.  I am getting an error when I use strSQL = "DELETE FROM QA_DAC where (TICKET_ID = TICKET_ID_VAR)". If I were to replace the TICKET_ID_VAR with a actual ticket ID it works fine.

The error that I am getting is a runtime error "TICKET_ID_VAR" : invalid identifier

Any suggestions on why it isn't passing?  I see that it is capturing the variable when I debug.
