From the following table, Calendar in Row 1 Starting in Col D,
and Data in Columns A, B, C Starting in Row 2.
I need to distribute the Men, using the Start Date and duration, while
skipping Fridays, saturdays and Sundays. Expected results shown
starting in Column D.

Sub CalDist()
Dim LastRow, LastCol As Long
Dim Dur As Integer ' Duration in Days
Dim Men, d As Integer
Dim Start As String ' Starting Date

LastRow = Range("A65536").End(xlUp).Row
LastCol = Range("IV1").End(xlToLeft).Column + 3

'Populating the Table
For r = 2 To LastRow
Dur = Cells(r, 2)
Men = Cells(r, 3)
For c = 4 To LastCol
Start = Cells(r, 1)
If Start = Cells(1, c) Then
'Distribute Men for the Duration
For d = 0 To Dur - 1
'---------------------------------------------------------------
' If Start Weekday = Friday, Saturday or Sunday, skip the Column
' Problem with the following If's.
' If the Start Date is already a Friday, Saturday or Saturday
' the If's are processed fine.
' If the Start Date is any other WeekDay and the Duration
' would go over the next Week, the If's are ignored.
' I cannot find my Error.
'---------------------------------------------------------------
If Weekday(Cells(1, c)) = 6 Then c = c + 1
If Weekday(Cells(1, c)) = 7 Then c = c + 1
If Weekday(Cells(1, c)) = 1 Then c = c + 1
Cells(r, c + d) = Men
Next d
End If
Next c
Next r
End Sub
