Hi Zakaria,

oPerson = createobject("Person")
oTime = createobject("Time")
oPerson.Init(oTime)
oPerson.GetAge()

this is not the way to pass parameters to the INIT event of an object.
The INIT is an event and not a method thats intended to be called by the developer.
Its called/fired automaticly during the creation process of that object. If you want to pass one or more parameters, you should use the additional parameters of the createobject() function.

oTime = createobject("time")
oPerson = createobject("person", oTime)
