    Solver Loop Macro Question

    Hello,

    First post ever on this forum, so I apologize if I'm doing in incorrectly...

    I should also preface this with saying I'm very new to VBA, and have only really used it a handful of times in the past.

    I'm looking to run a set of solver trials, each trial having a Goal, Value, and Changed Cell in a row. The solver run is to do this for quite a lot of rows.

    Here is the code I'm using, but it gives me a Compile error: Invalid qualifier statement then highlights the .Address portion of "ValueOf:=cellValue.Address(True, True).Value"

    Any suggestions on how to get around this?

    Sub solveAll()
    '
    ' Solver Macro
    '
    ' Keyboard Shortcut: Ctrl+Shift+D
    '
    Dim cellChange As Range
    Dim cellGoal As Range
    Dim cellValue As Range

    Set cellChange = ActiveSheet.Range("V4:V243")
    Set cellGoal = ActiveSheet.Range("U4:U243")
    Set cellValue = ActiveSheet.Range("S4:S243")

    Do '*****LOOP & Solve*****
    SolverReset
    SolverOk SetCell:=cellGoal.Address(True, True), MaxMinVal:=3, ValueOf:=cellValue.Value, ByChange:=cellChange.Address(True, True)
    SolverSolve UserFinish:=True
    SolverFinish KeepFinal:=1

    Set cellChange = cellChange.Offset(1, 0)
    Set cellGoal = cellGoal.Offset(1, 0)
    Set cellValue = cellValue.Offset(1, 0)

    Loop While Trim(cellGoal.Text) <> "" 'until goal cell is empty
    End Sub

    EDIT:

    After some tinkering, I've figured it out. I'll post my code here so others may be able to use it in the future. It was my initial Set cellChage/cellGoal/cellValue statements that were shown as ranges rather than just a single cell that caused the issue. Here is the code I'm using and it seems to work perfectly:

    Sub solveAll()
    '
    ' Solver Macro
    '
    ' Keyboard Shortcut: Ctrl+Shift+D
    '
    Dim cellChange As Range
    Dim cellGoal As Range
    Dim cellValue As Range

    Set cellChange = Range("V4:V4")
    Set cellGoal = Range("U4:U4")
    Set cellValue = Range("S4:S4")

    Do '*****LOOP & Solve*****
    SolverReset
    SolverOptions Precision:=0.001
    SolverOk SetCell:=cellGoal.Address(True, True), MaxMinVal:=3, ValueOf:=cellValue.Value, ByChange:=cellChange.Address(True, True)
    SolverSolve UserFinish:=True
    SolverFinish KeepFinal:=1

    Set cellChange = cellChange.Offset(1, 0)
    Set cellGoal = cellGoal.Offset(1, 0)
    Set cellValue = cellValue.Offset(1, 0)

    Loop While Trim(cellGoal.Text) <> "" 'until goal cell is empty
    End Sub


    The macro runs as long as there is something (usually 0 by default if my cellChange column is set to 0) in my cellGoal column. This can therefore be used for varying lengths of data.
