I have a calculation field where there should only be a numeric input.  I suppose there should be an isnumeric verification on the change event but I'm not sure how to write it.

Here's a easy way to not allow the end user to enter any non-digits value into a textbox..

  Private Sub Text1_KeyPress(KeyAscii As Integer)

    If Not ((KeyAscii >= vbKey0) And (KeyAscii <= vbKey9)) Then
      KeyAscii = 0
    End If

  End Sub

This will only allow the keys 0 to 9.

This would be a solution, it checks to make sure the input is numerical values and it will allow one decimal point (46 is the ascii code for the '.' character)...

  If Not ((KeyAscii >= vbKey0) And (KeyAscii <= vbKey9)) Then
    If Not ((KeyAscii = 46) And (InStr(Text1, ".") = 0)) Then
      KeyAscii = 0
    End If
  End If
