Not sure if this is possible and i dont have a clue how to do it.

I have a checkbox set (Setup;Participants)with a list of numbers from a value list determined by the field(Members;Member No).

I need a script that will go to the Layout Members and go to the relevant record based on the numbers being the same, of every member checked.

Eg

I check the numbers 1 4 and 6, the script will go to the layout members and go to the records with the member Numbers 1 4 and 6.

All help is greatly appreciated.

The neat thing about a checkbox is that it stores the checked values in a return-separated list. In a relationship, a return-separated list is called a multi-key. Each value in the list can match a value in a related table. So, all you have to is create a relationship from the check box field in the Participants table to the corresponding members field in the Members table. Once you have the relationship established, use a script with the Go to Related Record script step with the "show only related records" option checked to place the related members in a found set.

Its still not working it shows every record in the member layout

Did you make sure to check the option to "show only related records"? If so, post your file here so I can take a look at it.
