Mesh inflation on ANSYS fluent is not working

[Aarushi]

Hey everyone,

I am a student who is a beginner to CFD and I am having some problems while trying to do mesh inflation. When I am choosing named selections as my Boundary Scoping Method, the system won't allow me to select "Seal_With_Tag" as the named selection for the boundary option.

Here are some pictures of my program:

Thanks!
