Analyse resource usage in Excel Problem

[MarkC]

I am using this website to create a resource usage report in excel. It falls
over with "run-time rror 424 Object required" @ cboxTSUnits.List = myArray.

The sub-routine is:
Sub fillTSUnitsBox()
'sets Units constants
Dim myArray(5, 2) As String
myArray(0, 0) = "Days"
myArray(0, 1) = pjTimescaleDays
myArray(1, 0) = "Weeks"
myArray(1, 1) = pjTimescaleWeeks
myArray(2, 0) = "Months"
myArray(2, 1) = pjTimescaleMonths
myArray(3, 0) = "Quarters"
myArray(3, 1) = pjTimescaleQuarters
myArray(4, 0) = "Years"
myArray(4, 1) = pjTimescaleYears

cboxTSUnits.List = myArray
'use weeks as default value
cboxTSUnits.Value = 3
End Sub
