Function
 

I have been trying to create my own function whilst including othe
functions. Please see below example


Function ShiftHours(a, b, c, d, e)

ShiftHours = SumProduct(--(a = b), --(c = d), e)

End Function

This however doesnt work. Can i use functions within functions?

If so how would i use an aray function that would normaly require me t
use shift&Control&Enter at the same tim

Function
 

Function ShiftHours(a, b, c, d, e)

ShiftHours = Evaluate("SumProduct(--(" & a & "=" & _
b & "), --(" & c & "=" & d & "), " & e & ")")

End Function


Would be the basic approach. the contents of the variables would have to be
consistent with that approach to foster success.

Not like that

Function ShiftHours(a As Range, b, c As Range, d, e As Range)
Dim sFormula As String

sFormula = "SumProduct(--(" & a.Address & "=""" & b & """)," & _
"--(" & c.Address & "=""" & d & """)," & _
e.Address & ")"
ShiftHours = Application.Caller.Parent.Evaluate(sFormula)

End Function

Im thinkiing that as long formulas accross many cells can slow an excel
workbook down so its takes a few seconds to calculate using functions
could speed up the process ?

Putting the same formulas in functions would only make it slower.
