Answer 1

If you want to use a variable across pages, then consider using an Application Item instead of a Page Item. Application items are defined as shared components since they are shared between pages. An application item can be set in multiple ways, but for your question the following are relevant:

1. A Computation (shared components > Computations) for the application item with a computation point of "Before Header".
2. An Application Process (Shared Components > Application Processes) with a process point of "On Load: Before Header (page template header)"
