Date Format change

[mv8167]

I am trying to change the DateRequested from 2/27/2012 to 02-27-2012

my code is as such:

Code:

DateRequested = FormatDateTime(Date, 2)
Call DateManipulate(DateRequested)  'Insure date is MM/DD/YYYY format
year = Right(MM/DD/YYYY, 4)
month = left(MM/DD/YYYY, 2)
day = left(right(MM/DD/YYYY, 7), 2)
DateRequested = month & "-" & day & "-" & year

Public Function DateManipulate(eDate)

'Insure date is MM/DD/YYYY format
    Set MyDate = DotNetFactory.CreateInstance("System.DateTime")
    Set oDate = MyDate.Parse(eDate)
    DateManipulate = oDate.ToString("MM/dd/yyyy")
    eDate = DateManipulate
    'msgbox DateManipulate
    Set MyDate = Nothing

End Function

i am getting a Run Error: Overflow

What must i change? My date is returned as "02/27/2012"

(I found this code on the web and updated it with my values.)
