You can specify the order in which tags execute using the Timing Settings options. When you add 1 or more dependency they will execute before the tag you are configuring.
There are 3 tags A, B, and C. A must fire first, then B, and then C. In this scenario:
- A has no dependencies and will execute.
- A must execute before B, that is, B depends on A.
- C executes after B. C depends on B.
If A does not execute, then neither B nor C executes.
