I need someone to explain to me why this code constantly returns a 0 value when I attmept to run this program. I'm about at my witts end and ready to jump out of a window of a very tall building!

HTML Code:
Public Class FrmTravel
    'Define all variables to be used within the application
    'both locally and form wide.
    Dim decDays As Decimal
    Dim decAirfare As Decimal
    Dim decCarRentals As Decimal
    Dim sngMiles As Single
    Dim decParkingFees As Decimal
    Dim decTaxi As Decimal
    Dim decSeminar As Decimal
    Dim decLodging As Decimal
    Dim decTotalCost As Decimal
    Dim decAmountExempt As Decimal
    Dim decEndCost As Decimal
    Dim decMeals As Decimal             'price put in by user
    Dim decMealIncurred As Decimal      'price going in incurred txtbox
    Dim decMealTotal As Decimal
    Dim decMealExempt As Decimal        'going into the exempt txtbox



    'All constants listed.  Each value is the maximum 
    'amount that is reimbursable by the company.
    Const conMEALS As Decimal = 37D
    Const conPARKINGFEES As Decimal = 10D
    Const conTAXI As Decimal = 20D
    Const conLODGING As Decimal = 95D
    Const conPRIVATE As Decimal = 0.27D

    'Submit the calcMeals sub to determine the cost of food
    'and what is reimbursable.
    Function calcMeals() As Decimal
        decDays = CDec(cboDays.SelectedItem().ToString)
        decMeals = CDec(txtMeals.Text.ToString)
        decMealTotal = decMeals / decDays
        Return decMealTotal
    End Function
 


    Private Sub btnCalcCost_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalcCost.Click
        'process to begin reimbursement of money if any is due.
        If calcMeals() > conMEALS Then
            lblTotalCost.Text = FormatCurrency(CDec(calcMeals()))
        End If
I only have two subs posted here. I am continually getting a 0 when I hit the calc button. I believe the function is being called correctly and I have it in a logical statement correctly. Just looking for some incite.

Thanks,
Abe
