Action to update record in another table

[Griff]

I have a WeekView form that displays a table with days across and names down. I want to be able to click on a row and have it display the records for that name for that week (LinkToView) so I can update the schedule. To do that I think I need to 1. update the filter values used for a slice and then 2. display my LinkToView form based on that slice.

The question is how do I create an action that is available from my WeekView form that will update a value in another form? If I create an action called UpdateFilter for table Filter to set the value of my selected name, that Action is not available to the form WeekView because it is linked to the Filter table not the Names table.

Any suggestions?
