I have a file I use to reconcile 2 sets of numbers. What I would like is to
end the procedure the moment the difference between the numbers is 0.

The way my file works is that when the file is opened, I am prompted to
enter information into cells through a series of Input Boxes. At certain
points, I make the macro stop if the cell containing the difference equals 0.
It works great, but I would like to have the macro stop the moment the
difference = 0.

Here is my macro:

Private Sub Test()
'Enters information
Application.StatusBar = "Enter information."
Entry = MsgBox("Activate Wizard?", vbQuestion + vbYesNo, "Data Entry")
If Entry = vbYes Then
Application.Run (Macro)
Else:
Call Messages.Messages
End
End If
'Prompts to enter Target and Data1
Range("Target").Value = InputBox("Enter target figu", "Wizard: Target")
Range("1").Value = InputBox("Enter Figure1 amount:", "Wizard: Figure1")
Range("2").Value = InputBox("Enter Figure2 amount:", "Wizard: Figure2")
Range("3").Value = InputBox("Enter Figure3 amount:", "Wizard: Figure3")
If Range("Difference").Value = 0 Then
Sheets(2).Activate
End
End If
'Prompts to enter Data2 if Difference < 0
Data2 = MsgBox("Is there Data2?", vbQuestion + vbYesNo, "Data2")
If Data2 = vbYes Then
Range("4").Value = InputBox("Enter Figure4 amount:", "Wizard: Figure4")
Range("5").Value = InputBox("Enter Figure5 amount:", "Wizard: Figure5")
Range("6").Value = InputBox("Enter Figure6 amount:", "Wizard: Figure6")
End If
If Range("Difference").Value = 0 Then
Sheets(2).Activate
End
End If
'Prompts to enter Data3 if Difference < 0
Data3 = MsgBox("Enter Data3?", vbQuestion + vbYesNo, "Data3")
If Data3 = vbYes Then
Range("7").Value = InputBox("Enter Figure7:", "Wizard: Figure7")
Range("8").Value = InputBox("Enter Figure8 amount:", "Wizard: Figure8")
Range("9").Value = InputBox("Enter Figure9:", _
"Wizard: Figure9", Abs(Range("Difference").Value))
End If
'Displays report
Sheets(2).Activate
Call Messages.Messages
End Sub

You'll notice the recurring code:

If Range("Difference").Value = 0 Then
Sheets(2).Activate
End
End If

I want to enter that once in my module and execute that IF statement the
moment it is true. Thanks.

(The numbered range names are fake; I know they are illegal in Excel)

I am running on Excel 2003, unless otherwise stated.

Just a note:
I would like this to start searching after I enter my target figure.

I found a workaround with a separate procedure I call after each point in
data entry.
