Hi anybody,
trying to get a more interactive form I am pursuing to chain two dynamic double dropdowns(that works fine individually)
I have got they are in the same form with some JavaScript code("selección" is the global variable that is passed to ajax)

function igual1(){
$('seleccion').value=$('provincia1').value;
}
function igual2(){
$('seleccion').value=$('provincia2').value;
}

the new challenge is how can I chain them: if i select provincia1 and after hospital1 how to get the same values on next "double dropdown" provincia2->hospital2 (actually there are 6 more)
I have tried with some JavaScript code but I am lost
