Dependant Dropdown

Hi

I have tried to create a dependant dropdown in a form using a code I copied from another link.

It appears to be working at first, users can select an item from the first dropdown and this then populates the options in the second dropdown and these can also be selected.  However, when the form is saved and is re-opened the second dropdown defaults to "Please Select".  I have copied the code below, can anyone tell me what I've done wrong?

Thank you

Yvonne
