get value from control of one page to control of another page

Hi All

I have two pages: Page1 and Page2. I want to get value of the control from Page1 to Page2.

The Control that should be get from Page1 is with source erp of global variable which value is calculated in a On validate trigger of corresponding control.

Page1 and page2 are independent. Only I need value of control from 1 to Page2.

I tried with :

CurrPage.Contol1 := Page2(Page2 is a global variable with type Page).Control2 , but this is not possible.

Thanks in Advance

Is there some Navision function for this?
