Calculating age function

I am trying to use that function to calculate the age of a person in years, months, and days. I typed this function in a module and would want the result based on Date of Birth displayed in a text box on a form. MY PROBLEM IS ON HOW TO HAVE THE RESULT RESULT DISPLAYED IN A TEXT BOX. I entered the aSns=yer & "years"& mon &"month(s)"& d &"day(s) old." expression in the controlsouse property but unfortunately I am getting a #Name error in the text box. Can someone help me with how how best I can end up with the age in the text box.

Public Function ExactAge(Date_of_Birth As Variant) As String

Dim yer As Integer, mon As Integer, d As Integer
Dim dt As Date
Dim sAns As String

If Not IsDate(Date_of_Birth) Then Exit Function
dt = CDate(Date_of_Birth)
If dt > Now Then Exit Function

yer = Year(dt)
mon = Month(dt)
d = Day(dt)
yer = Year(Date) - yer
mon = Month(Date) - mon
d = Day(Date) - d

If Sgn(d) = -1 Then
d = 30 - Abs(d)
mon = mon - 1
End If

If Sgn(mon) = -1 Then
mon = 12 - Abs(mon)
yer = yer - 1
End If

sAns = yer & " year(s) " & mon & " month(s) " & d _
& " day(s) old."

ExactAge = sAns

End Function

I dont understand. Your code seems to work.
i entered 09/11/1973 into text one and clicked the command
button. text2's out put was.......27 year(s) 1 month(s) 8 day(s) old.
So it seems to work????


Private Sub Command1_Click()
Dim dob As Variant
dob = Text1.Text
ExactAge (dob)
End Sub



Public Sub ExactAge(dob As Variant)

Dim yer As Integer, mon As Integer, d As Integer
Dim dt As Date
Dim sAns As String


dt = CDate(dob)
If dt > Now Then Exit Sub

yer = Year(dt)
mon = Month(dt)
d = Day(dt)
yer = Year(Date) - yer
mon = Month(Date) - mon
d = Day(Date) - d

If Sgn(d) = -1 Then
d = 30 - Abs(d)
mon = mon - 1
End If

If Sgn(mon) = -1 Then
mon = 12 - Abs(mon)
yer = yer - 1
End If

sAns = yer & " year(s) " & mon & " month(s) " & d _
& " day(s) old."

Text2.Text = sAns

End Sub
