Measures and calculated dimensions are not selectable. Selections are global to the entire app, but expression values and calculated dimension values exist only on the context of the pivot table. So selections can only be made against actual field values.
Even selecting a calculated dimension value selects the underlying field values.
You will need to look for an different way to resolve this issue.

As @jontydkpi mentioned, what you want to accomplish is not possible. If you do want this possibility, you should create the value of 425 in your data model and get the value in a table as a dimension.
