As another solution based on the discussion in the comments you may be want to place something like this in your Minicart template (app/design/frontend/[theme]/[theme]/template/checkout/cart/minicart/items.phtml).
Please note, that this snippet never really got optimized nor revised as it was a quick fix in a particular situation some long time ago.

Even if alert(totalvalue); for example would return 100 it most likey is still just a string rather than a number. You can check that by alert(typeof(totalvalue)); // expected result in this case is 'string'.
So you will have to convert that string to a number using something like totalvalue = Number($j('#valor_produto').val()); or 'ecomm_totalvalue': Number(totalvalue). If you now alert(typeof(totalvalue)); you should get prompted number.
So, for example:
(function(){
try {
url_atual = $j('#urlAtual').val();
alert(url_atual);
if(url_atual == "catalog"){
var prodid, totalvalue;
//page product/category
totalvalue = Number($j('#valor_produto').val()); // forcing type "number" rather than default "string"
prodid = $j('#id_produto').val();
alert(totalvalue);
alert(prodid);
dataLayer.push({
'event': 'fireRemarketingTag',
google_tag_params: {
'ecomm_prodid': prodid,
'ecomm_pagetype': 'product',
'ecomm_totalvalue': totalvalue // added missing quotes
}
});
}
else if (url_atual == "ajax") {
var prodid, totalvalue;
//cart
console.log('entrou carrinho');
dataLayer.push({
'event': 'fireRemarketingTag',
'google_tag_params': {
'ecomm_prodid': prodid,
'ecomm_pagetype': 'cart',
'ecomm_totalvalue': totalvalue
}
});
}
else if (url_atual == "cms") {
var prodid, totalvalue;
//other pages/cms
dataLayer.push({
'event': 'fireRemarketingTag',
'google_tag_params': {
'ecomm_prodid': prodid,
'ecomm_pagetype': 'purchase',
'ecomm_totalvalue': totalvalue
}
});
}
else {
dataLayer.push({
'event': 'fireRemarketingTag',
'google_tag_params': { }
});
}
}
catch (err) {}
}) ();
For easy debugging:
One easy way to test google-snippet integrations is using the Tag Assistant (by Google) Google Chrome extension (Tag Assistant on chrome.google.com).
