checkout在magento1.7中不起作用

Question

I have a multistore done in Magento 1.7. Checkout is not working in one store. Nothing is happening after clicking the continue button inside Billing Information block which calls the function onclick="billing.save()". I checked with firebug all blocks are coming correctly. I think the problem is with the function billing.save(). Where I can find this function.

EDIT

I have checked my response in transport.responseText in billing.save() for one store I am getting response like this

{"goto_section":"shipping_method","update_section":{"name":"shipping-method","html":"<dl class=\"sp-methods\">
<p>We are shipping daily until 12.19.2011 although most orders will arrive for the Holidays, we can not guarentee 12.25.2011 delivery (for orders placed after 12.14.2011). <span style=\"color:red;\">We begin shipping again in January - Order Honeybells Now!<\/span><\/p>

        <dd>
            <ul>
                            <li>
                                                                   <span class=\"no-display\"><input name=\"shipping_method\" type=\"radio\" value=\"flatship_flatship\" id=\"s_method_flatship_flatship\" checked=\"checked\" \/><\/span>
                                                <label for=\"s_method_flatship_flatship\">Standard US                                                                        <span class=\"price\">$12.00<\/span>                                                <\/label>
                                   <\/li>
                        <\/ul>
        <\/dd>
    <\/dl>
"},"allow_sections":["shipping"],"duplicateBillingInfo":"true"}

and for the store which is not working its coming like this

<meta name="google-site-verification" content="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" />
{"goto_section":"shipping_method","update_section":{"name":"shipping-method","html":"<dl class=\"sp-methods\">
<p>We are shipping daily until 12.19.2011 although most orders will arrive for the Holidays, we can not guarentee 12.25.2011 delivery (for orders placed after 12.14.2011). <span style=\"color:red;\">We begin shipping again in January - Order Honeybells Now!<\/span><\/p>

                                                                   <span class=\"no-display\"><input name=\"shipping_method\" type=\"radio\" value=\"flatship_flatship\" id=\"s_method_flatship_flatship\" checked=\"checked\" \/><\/span>

                        <\/ul>
        <\/dd>
    <\/dl>
"},"allow_sections":["shipping"],"duplicateBillingInfo":"true"}

I don't know from where this meta tag is coming and when I alert response.update_section.name in side setStepResponse: function(response){ its coming as undefined...

EDIT 2

Now meta tag problem has been solved.. They have added that meta tag inside index.php of their sub domain folder. Now the problem is when I place order it displays

Gateway error: (TESTMODE) The merchant login ID or password is invalid or the account is inactive.

Any one has any idea please help me. Its working fine in another store. I am using Authorize.net for payment and enabled Test Mode.

Answer 1

This function can be found in

skin/frontend/your_package/your_theme/js/optcheckout.js

or, if it's not in /your_package/your_theme/ and /your_package/default/, it's in /base/default/

In Magento 1.7 is should be in the line 302 of the file (if nothing was modified).

But I don't think the problem is there. Have you checked the response for saveBilling in Firebug/Developer Tools?
