VBA Solver - Stuck at "Setting up Problem"

Hi!

Im trying to make a solver function work but it is now stuck at "Setting up problem" anything i can do with this? All cells have been named in my excel sheet so im assuming i can put those names into the code instead of e"C48". The math behind the solver is not that advanced either, so it doesnt make sence to me why it wont go further then setting up problem.
I also added the excel sheet itself.
Any help would be appreciated
Code:

Sub SolverFB()


Worksheets("Data Sheet").Activate

SolverOk SetCell:=Range("Freeboard"), MaxMinVal:=3, ValueOf:=1.5, ByChange:=Range("Ballast_weight,Length")

SolverAdd CellRef:=Range("Length"), Relation:=3, FormulaText:=("Length_min")
SolverAdd CellRef:=Range("Length"), Relation:=1, FormulaText:=("Length_max")

SolverAdd CellRef:=Range("GM"), Relation:=3, FormulaText:=Range("GM_min")
SolverAdd CellRef:=Range("GM"), Relation:=1, FormulaText:=Range("GM_max")

SolverAdd CellRef:=Range("Freeboard"), Relation:=3, FormulaText:=Range("FB_min")
SolverAdd CellRef:=Range("Freeboard"), Relation:=1, FormulaText:=Range("FB_max")

SolverSolve userFinish:=True


End Sub

"Freeboard <= 1,5" and "Freeboard >= 1,5" came in cause i forgot to remove the constraint for freeboard. Thanks for checking it out, ill try and see what i get!

Not sure how my cells got formated as Text but i changed those and it fixed it. Thanks for the help!

You are welcome and thanks for feedback
