How to build a formula on values and operators defined in cells

As a solution, I created a function to use that evaluates the data in my table based upon what I send it. It returns TRUE or FALSE. 

=IF(AND(EvaluateYearlyPenaltyExpression(C42,'Common For All'!A132,'Common For All'!B132),GetYearlyPenaltyExpression(C42,'Common For All'!C132,'Common For All'!D132)),'Common For All'!H132,0)

Function EvaluateYearlyPenaltyExpression(income As Currency, comparisonoperator As String, threshold As Currency) As Variant
  Dim compareop

  compareop = UCase(Trim(comparisonoperator))

  idx = InStr("AND,OR,XOR", compareop)

  If idx > 0 Then
    'Build expression using Excel logical function (AND(), OR(), XOR()).
    expr = compareop & "(" & income & "," & threshold & ")"
  Else
    'Build and expression like "x + y", "x < y", ...
    expr = income & compareop & threshold
  End If

  EvaluateYearlyPenaltyExpression = Evaluate(expr)
End Function
