Objects and invalid use of property
I have several objects, one is Crew class that keeps track of a company that does a service, the other one is Service class. Service class keeps track of bigger picture, so I need to be able to add multiple Crew objects to the same Service object. The problem is that I keep getting "invalid use of property" error.
This is the line that creates the error: Service.Crews Crew and below is full code.
Code:
Sub test()
Dim cell As Range, techs As Single, multiTech As Boolean
Dim Crew As cCrew, Service As cService, Equipment As cEquipment
multiTech = False
Set Crews = New Collection
Set Crew = New cCrew
Set Cleanway = New cCleanway
Set Service = New cService
' create a crew for each line item
For Each cell In Range("Labor_Info")
If IsEmpty(cell) Then Exit For
Set Crew = New cCrew
With Crew
.Code = cell
.ServiceStart = cell.Offset(0, 2)
.ServiceEnd = cell.Offset(0, 3)
.InitialRate = cell.Offset(0, 8)
.AdditionalRate = cell.Offset(0, 9)
.TechCount = cell.Offset(0, 1)
End With
Service.Crews Crew
' update sheet values
cell.Offset(0, 4) = Crew.CalculateHours
cell.Offset(0, 5) = Crew.TotalServiceTime
Next cell
MsgBox "ok"
End Sub

Thank you.
