On a form, create a textbox for Field1. On its property sheet, call it name. Create two more text boxes. I name them firstname, lastname. This is on their property sheet. Click on the text box that's bound to Field1, go to the Event tab of the control and click on After Update. Click on the build button (...) and type in the following

or just copy and paste from here)
Private Sub name_AfterUpdate()
Dim SPos As Integer, EPos As Integer
Dim s As String
Dim SLPos As String, FLen As String
s = Me![name]
SPos = 1
EPos = InStr(SPos, s, "/"

- 1
Me![firstname] = Trim(Mid(s, SPos, EPos))
SLPos = InStr(s, "to "

+ 3
FLen = Len(s)
Me![lastname] = Trim(Mid(s, SLPos, FLen))
End Sub
As long as your field is the way you presented it, especially the part "server1 to server2", then this will put the name in the first text box and server2 info in the second text box. I'm in a hurry so I didn't do the middle part yet. If I do it, I'll post it, but this may help you in your programming. Don't forget in the SLPos line, it's the word to and a space inbetween the quotes.
