i want to control two drop down lists to tell which macro to be run automatically

Currently i have this code

Private Sub Worksheet_Change(ByVal Target As Range)

Application.EnableEvents = True ' <-- just for tests
If Not Intersect(Target, Range("C1")) Is Nothing Then
  Select Case Target.Value  
   Case "Expander 1 eff"     
      CopyIncreaseRecord      
      Case "Expander 2 eff"  
     CopyIncreaseRecord       
      Case "Pump eff"  
       CopyIncreaseRecord     
      Case "Net Power"  
      CopyIncreaseRecordNetPower      
   End Select 
End If

End Sub

under the Sheet5 (Graph1) view code.

presently i'm using one drop down in cell C1 to tell which macro to run automatically when i select an option in cell C1,

now i want to have two drop downs in cell C1 & in cell C2, for example if C1 is selected "Expander 2 eff" and C2 is selected "Cycle eff" i want macro Expander2effvsCycleeff to run if C1 is selected "Expander 2 eff" and C2 is selected "Massflowrate" i want macro Expander2effvsMassflowrate to run.

pls help, thanks in advance

i tried AI but it is not giving me the selection in two cells to be met
