How do I take the value from a summary in table 1, and show it in table 2? Portals don't work, creating a field that links to the summary doesn't work.

Are you using a calculated summary field (using GetSummary)?

No, I am using a summary field, not a calculation field.

Just take the summary field from table 1 and place in on a layout for table 2. If the two tables are properly linked (check your Relationships Graph) you will see the appropriate summary displayed.

My problem is in the relationship graph my summary fields are greyed out. I also already have a join file in between table 1 and 2.

Summary fields are context sensitive in the sense that the value they return is dependent upon the found set for summmary fields in a trailing grand summary part and upon found set and sort order in a subsummary part. I'd try defining a calculation field using the GetSummary() function and using this field in the related table. As an alternative, you can define a calculation field using the Sum(relationship::field) function in the related table. The relationship will determine the set of records aggregated.
