Pb to submit a form

Hi everybody, I've got a huge problem and I don't know how I can solve. I hope that you guys can help me. I'd like to test a form to know if all fields are well fullfill before sending this form to my php script. The pb comes with a multiple select statement. To be able to test it in Javascript, I should have : <select multiple name="languages"> and I can do document.myform.languages.selectedIndex to know if something was selected. But if I do so, I can only read the last selected option in my php script. The pb is that to be able to read all selections, that user made, from my php script I should have : <select multiple name="languages[]"> and so I can't test it in javascript ( document.myform.languages.selectedIndex doesn't work document.myform.languages[].selectedIndex doesn't work neither document.myform.(languages[]).selectedIndex doesn't work neither ) Is anybody aware of this and know how I can solve it ?
