Calc problems

[soylatino]

Hi,

i try to make a calc process. The goal is:
if one option from multi select is selected, the price is 15,
if 2 options from multi select is selected, the price is 30,
if 3 options from multi select is selected, the price is 45,
if all option from multi select is selected, the price is 55,

Here is the code i wrote. It does not work:

jQuery(function ($) {
var calculate = function () {
var total = 0;
// Check the selected options of a multi select menu
var val1 = $(‘.quform-field-2_34’).val();
if (val1) {
if ($.inArray(‘opt1’, val1) = 1) {
total += 15;
}
if ($.inArray(‘opt2’, val1) = 1) {
total += 30;
}
}
if ($.inArray(‘opt2’, val1) = 3) {
total += 45;
}
if ($.inArray(‘opt2’, val1) = 4) {
total += 55;
}
}

// Display the result to the user
$(‘#form-total’).text(‘Total: $’ + total);

// Set the value of the hidden field
$(‘.quform-field-2_38’).val(‘$’ + total);
};

// Calculate on page load
calculate();

// Recalculate when these select menus are changed
$(‘.quform-field-2_34’).change(calculate);

});

Thank your for your help.
Best regards
