I've tried using Application.Volatile and I've made sure that updates are set
to automatic already.. Is there a way to turn the following UDF into a normal
function?

Function SalesTotal() As Integer
Application.Volatile
Dim varDate As Date
Dim c As Range
varDate = ActiveCell.Offset(-1).Value
SalesTotal = 0
LastRow = Sheet19.Cells(Rows.Count, "M").End(xlUp).Row
Set MyRange = Sheet19.Range("M1:M" & LastRow)
For Each c In MyRange
If c.Value = varDate Then
SalesTotal = (SalesTotal + c.Offset(, 2).Value)
End If
Next
If IsError(SalesTotal) Then SalesTotal = 0
End Function

Hi guys, I have a function running in my workbook and it won't recalculate
automatically. I have an idea this is because it's being used 365 times on
one sheet. Is there any way to make this update automatically or do I need
to redesign this thing again?
