In model driven apps,

I have SMART Audit Visit table and form $($as shown in image$).$

arb$\_$Customer $($lookup column to SMART Audit Customers table$)$

arb$\_$Site$($lookup to Customer postal address$)$

In SMART Audit Customer table $-$

arb$\_$Customer $($Lookup to Customers V$3$table$)$

Customer ID$($primary auto number column$)$

Need JavaSript to:

Get Customer lookup from Smart Audit Customers,

Use this to filter Customer postal addresses table view.

In SMART audit customers $-$ arb$\_$customer looks up to Customers V$3$ table and primary column there is mserp$\_$customeraccount.

In Customer postal address in which I want to filter is by mserp$\_$customeraccountnumber.

So in filter these are comparing.

In the image form Customer can be CUS$-001.$ But as this looking to SMART Auidt Customers, there arb$\_$Customer is C$-009($looking to Customers V$3).$ So we want to show only the dropdowns in arb$\_$Site to show C$-009$ from mserp$\_$customeraccountnumber $($Customer Postal Address$)$
