How do I automatically delete records that contain a relationship

Here's the problem,

I have 2 tables

Tabel 1 contains the names of people

PersonID - AutoInc / PrimaryKey
PersonName

Table 2 contains Wdigets with the field PersonID being the relationship to people

WidgetID AutoInc/PrimaryKey
PersonID (relationship with Table1)
WidgetName

OK Now the challenge; Just say a person with the name David has 20 entries in the Widget Table and i now want to delete the perosn from the database, Easy enough to delete the person from the table but then I have all these entries left in the Widgets table with a relationship to David that does not exist.

How do I update or delete fields containing to each other in 2 databases?

Thanks

add another delete record behavior. you can use the same variabel from the first delete record behavior that contains the person ID and select the PersonID column as the key column.

But in Table 2 there may be 600 records I need these to be deleted in the main person has been removed from table 1. It needs to repeat somehow, the delete multiple records didn't work as required a repeat region which obviously we don't have.

Actually would this work,

DELETE FROM `Table2` WHERE `PersonID` = a$

the single record delete will actually delete multiple records if you select the Foreign key column as the key column and pass in the variable that creates the relationship.
