Lookup of related field not working

Hi,

I have a master file called “quote” and a history file called “quote_Products”

From the “quote” when I select the products it creates relational records in the history file with the quote_id, product_id etc.. Upto this no problem

I have a field called product_title in the “quote_Products” and I set the Auto enter option this field so that the product_title is looked up from the “product” table using the relation called “quote_product_to_product” (key field is product_id)

This is not working.. No values are auto entered

But when I go the “quote_product form” and manually cleared the product_id and re-entered the value is looked up..

Can you please.. check?

Thanks

Could you pls post a sample file demonstrating this problem?
