If I want to run a macro every half hour, do I use the
OnTime method? This is what I have tried:

Dim KeepingTime As Boolean
Dim Times As Long

Times = 10

KeepingTime = True

Do While KeepingTime = True

Application.OnTime Now + TimeValue
("00:30:0"), "GetAll"

Times = Times - 1

If Times < 1 Then
KeepingTime = False
End If
Loop
