SYMPTOMS
In Microsoft Excel 2000, when you execute the SolverAdd function to programmatically add a constraint in your Solver model, the constraint is not added.



CAUSE
This problem may occur if you use R1C1 notation for the  argument of the SolverAdd function. In Microsoft Excel 2000, the  argument for SolverAdd will execute successfully only when specified in A1 notation.

NOTE: In versions of Microsoft Excel earlier than Excel 97, when you add a constraint to a problem with the Visual Basic function SolverAdd, you are required to specify the right side of the equation (the  argument) in R1C1 notation. If you do not specify the  argument in R1C1 notation, the constraint is not added. This was changed in Microsoft Excel 97, and now you must specify the  argument in A1 notation.

The following line will not add a constraint to a Solver model in Microsoft Excel 2000: SolverAdd CellRef:=Range("$A$1"), Relation:=1, FormulaText:="R1C2" To work around this problem, change the  argument to A1 notation, as in the following example: SolverAdd CellRef:=Range("$A$1"), Relation:=1, FormulaText:="$B$1"
