Autofill doesn't work

Hi...

I have this problem with the autofill feature:

If I use the table_kilometers to enter the data, Phprunner correctly import PHPRunner last record of the Kilometers on a specific vehicle.

But if I make the relationship in the page named TABLES (the first of PHPRunner) table_vehicle and table_kilometers linked by id_veichle, when i go to the veichle page i can insert record in the table_kilometers and the system get id_veichles automatically. But in this case PHPRunner doesn't autofill the record with the last Kilometers.
