Reapeting group different things

[Helmar]

I need to have text from two different things in one reapeting group.
I have a table for RiskPlan
And a table for RiskDescription

When a new RiskPlan thing is created I store the unique ID from the RiskDescription thing in the RiskPlan thing and call it RiskEventID (I use these on another page to mach the things)

In the repeating group I want a text with the RiskEvent from RiskDescription and responsible from RiskPlan.
How do I match up these texts?

When you think long and hard about it… it slowly makes sense
