I am trying to run this piece of code but I am getting nothing but the first
constraint in the Solver. I'd be happy is someone could help me with this.
Thanks..

Public Sub DualSolver(K, M, N)
'Activate the DLP sheet
Sheets("DLP").Activate

'Reset the solver
SolverReset

'Objective Function
SolverOk SetCell:=Range("B4"), MaxMinVal:=1, ValueOf:="0",
ByChange:="Range(Cells(2, 2), Cells(2, M + N +
1)),Range(Cells(1,M+N+6),Cells(K,M+N+6))"

'Constraints

SolverAdd CellRef:=Cells(K + 1, M + N + 6), Relation:=2, FormulaText:="1"
SolverAdd CellRef:=Range(Cells(6, 2), Cells(6, M + N + 1)), Relation:=2,
FormulaText:="Range(Cells(8, 2), Cells(8, M + N + 1))"
