Test to see if any of the three items in your "or" statement actually equal "true"

[Taifun]

a listview selection property never will be true or false, it will be the value selected from the listview

use a global variable and set it to true in the 3 Listview.AfterPicking events
then in your timer event check that global variable

[TIMAI2]

What are your three selections, as @Taifun said, none of them are likely to equal true...
