creating a workday calculator on access form

[buddyr]

Hello,
I have 3 fields dateout, datein, TurnAroundNumber(number).
I used this code in module:

Function GetDateOut(dDate As Date, Span As Integer) As Date
Dim j As Integer, i As Integer, dtStart
dtStart = dDate
For j = 1 To Span
    dtStart = dtStart + 1
    Do While Weekday(dtStart) = 1 Or Weekday(dtStart) = 7 
        dtStart = dtStart + 1
        i = i + 1
    Loop
Next
GetDateOut = DateAdd("d", i + Span, dDate)
End Function

in a calculate command button I made the call:
me.[dateout]=getDateOut(me.dateIn, me.TurnAroundNumber)

I notice if the turnaroundnumber textbox is empty I get a null error.
Can I stop that from happening?
and can I place this in a subform and not adversely effect other objects and subforms.
Thank you

Something like this

If Not IsNull(me.TurnAroundNumber) Then
  me.[dateout]=getDateOut(me.dateIn, me.TurnAroundNumber)
Else
  Msgbox "This Computation Cannot Be Run When Turn Around Number Is Blank!"
End If
