Run Solver Multiple Times (while changing constraints and goal for each iteration)

Hi All,
First of all, I am new to the Excel Forum, and have a problem to start out with.

I am having some trouble with getting VBA to run the solver. I have already gone through adding the solver add-in as well as checking solver in VBA References.

I would like solver to run multiple times, while after each time solver runs, I want to increase the row count for all goals and constraints.

I am encountering an error message: "Run-time error '438': Object doesn't support this property or method" on my SolverOK line.

Any suggestions?
Thanks!

Dim cellConstraintTotalPayed1 As Range
Dim cellConstraintTotalPayed2 As Range
Dim cellConstraintTotalPayed3 As Range
Dim cellConstraintIntCharged1 As Range
Dim cellConstraintIntCharged2 As Range
Dim cellConstraintIntCharged3 As Range

Set cellChange = ActiveSheet.Range("S17:U17")
Set cellGoal = ActiveSheet.Range("V18")
