<p>Very successfully doing autofill based on Patrick's 'Auto-populate a textbox based on dropdown' article with a single dropdown updating a number of fields. </p> <p>But if there are two or more dependant dropdowns, although the dependant dropdowns work fine and filter each other, I am getting two problems - </p> <p>1 - When the first dropdown is changed it briefly displays the correct values in the autofill fields but then does a refresh - and the fields then display blank or previous values </p> <p>2 - If the second dropdown only has one selection the fields it should update are not updated </p> <p>How can I autofill with multiple dropdowns? </p>
