Here is an example of using sub signatures
1. Random Advertisements
Using @Formula it is possible to create a set of advertisements.
The following formulas are added to three seperate sub signatures. Only one of the formula will evaluate to @True
@if(@Second(@Created) >= 0 & @Second(@Created) <20 ;@true;@false)
@if(@Second(@Created) >= 20 & @Second(@Created) <40 ;@true;@false)
@if(@Second(@Created) >= 40 & @Second(@Created) <60 ;@true;@false)
