UET Fields as Synchronized Lists?

[Ross Culver]

Can you use an UET field as a linked subform or subcategory linked (synchronized) by a key field?

In other words, can I use an UET field in a drop down combo box listing only those email addresses pertaining to the customer shown on the screen?

Can I use the Validation expression in the Class/Field setup to denote the link? (i.e. where customer.cust-num= ? and customer.cust-seq=?)?

Thanks,

Ross
