when error notice flags ready state , status both come 0, thrownerror error.

also receiving controller print_r(&_post) test.

i don't seem able past myself, if can appreciated.

thanks

the keys of data object should not in quotes.

it should work (provided jquery calls values work) when change to:

data: {     currency_sel: $('#currency_sel :selected').val(),     language_sel_1: $('#language_sel_1 :selected').val(),     language_sel_2: $('#language_sel_2 :selected').val() },
