Excel Solver Error while using VBA

Question

I have the following code which is basically a macro recorded. after recording the macro, I cleaned away some lines of code that were found repetitive. When I try to run this code again I get a Sub or Function not defined error. I checked out other Solver VBA questions on Stackoverflow and I dont seemt to be doing anything wrong. Can anyone please help? Thanks in advance.

Sub Macro2()

SolverOk SetCell:="$BF$7", MaxMinVal:=2, ValueOf:=0, ByChange:="$BA$7:$BC$7", Engine:=2, EngineDesc:="Simplex LP"

SolverAdd CellRef:="$BA$7", Relation:=4, FormulaText:="integer"
SolverAdd CellRef:="$BA$7", Relation:=3, FormulaText:="0"

SolverAdd CellRef:="$BB$7", Relation:=4, FormulaText:="integer"
SolverAdd CellRef:="$BB$7", Relation:=3, FormulaText:="0"

SolverAdd CellRef:="$BC$7", Relation:=3, FormulaText:="0"
SolverAdd CellRef:="$BC$7", Relation:=4, FormulaText:="integer"

SolverAdd CellRef:="$BE$7", Relation:=3, FormulaText:="0"

SolverOk SetCell:="$BF$7", MaxMinVal:=2, ValueOf:=0, ByChange:="$BA$7:$BC$7", Engine:=2, EngineDesc:="Simplex LP"

SolverSolve
End Sub

The Solver is an add in, so it won't work in your vba code until you enable it. I use 07, so you click office button -> options -> add-ins -> manage add ins to enable it. Not sure about other versions.

Once you have enabled the add-in, you must then connect the add-in to the vba editor. Open the VBA Editor (Alt+F11), then go to Tools -> References, then check off "SOLVER" and hit OK.
