# Reducing a list of numbers cleanly

Hi there,

Hoping someone can help me out, if you can many thanks in advance!

As an example i have a limited edition range of shoes, i can select the number of the range from a data validation list in cell A1. For this example i have set this pair of shoes to have a limited edition of 100 units. Is it possible to enter an amount of shoes i'm making into cell B1 and each time i do that it reduces my available limited edition amount?

A1 = shoes 100 from drop down list
B1 = I enter 10, press enter and the box clears for re-use but minuses the 10 from 100
C1 = summed to start with chosen A1 range then remove all entries in B1 (So currently would be 90)

I'm not sure if I understood correctly but try this: Copy and paste this macro into the worksheet code module. Do the following: right click the tab name for your sheet and click 'View Code'. Paste the macro into the empty code window that opens up. Close the code window to return to your sheet. Enter a value in B1 and press the RETURN key.
VBA Code:
``````Private Sub Worksheet_Change(ByVal Target As Range)
If Target.CountLarge > 1 Then Exit Sub
Application.EnableEvents = False
If Target.Address(0, 0) = "B1" Then
Range("AA1") = Target
Target.Offset(, 1) = Target.Offset(, -1) - Range("AA1")
Target.ClearContents
Range("AA1").ClearContents
End If
Application.EnableEvents = True
End Sub``````
