Security Filter across multiple tables

[jkib]

I need help with creating a security filter.
Situation:
I have 3 tables total.
Table 1 contains my data (Name, Amount Spent, Address)
Table 2 contains a reference between the name from Table 1 and the email (Jon Doe, jdoe@email.com)
Table 3 is a form in which I would like the security to filter through the data and only allow the USEREMAIL() to view their data from Table 1 and be able to make corrections to the Amount Spent.
