SYMPTOMS
In Microsoft Excel 98 Macintosh Edition, when you run 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 "FormulaText" argument of the SolverAdd function. In Microsoft Excel 98, the "FormulaText" argument for SolverAdd will run successfully when it is in A1 notation.

NOTE: In earlier versions of Microsoft Excel, 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 "FormulaText" argument) in R1C1 notation. If you do not specify the "FormulaText" argument in R1C1 notation, the constraint is not added. However, in Microsoft Excel 98, you must use A1 notation.



WORKAROUND
Microsoft provides programming examples for illustration only, without warranty either expressed or implied. This includes, but is not limited to, the implied warranties of merchantability or fitness for a particular purpose. This article assumes that you are familiar with the programming language that is being demonstrated and with the tools that are used to create and to debug procedures. Microsoft support engineers can help explain the functionality of a particular procedure, but they will not modify these examples to provide added functionality or construct procedures to meet your specific requirements. For example, the following line will not add a constraint to a Solver model in Microsoft Excel 98: SolverAdd CellRef:=Range("$A$1"), Relation:=1, FormulaText:="R1C2" To correct this problem, change the FormulaText argument to A1 notation, such as the following example: SolverAdd CellRef:=Range("$A$1"), Relation:=1, FormulaText:="$B$1"
