Prestashop 1.6.1.4 : product combination generator

[matteo.enter]

Hi,
I insert the attributes into the tables with a script in php that reads it from an ascii file.
If I generate the product combinations with another script in php I have no problem, but if I use the prestashop product combinations generator i have this error when I select attributes to generate the combinations:

 

ReferenceError: i18n_tax_exc is not definded​

 

I see into "attributes.js"  this lines :

 

 

 

function create_attribute_row(id, id_group, name, price, weight)
{
 var html = '';
 html += '<tr id="result_'+id+'">';
 html +=   '<td><input type="hidden" value="'+id+'" name="options['+id_group+']['+id+']" />'+name+'</td>';
 html +=   '<td>'+i18n_tax_exc+'<input id="related_to_price_impact_ti_'+id+'" class="price_impact" style="width:50px" type="text" value="'+price+'" name="price_impact_'+id+'" onkeyup="calcPrice($(this), false)"></td>';
 html +=   '<td>'+i18n_tax_inc+'<input id="related_to_price_impact_'+id+'" class="price_impact_ti" style="width:50px" type="text" value="" name="price_impact_ti_'+id+'" onkeyup="calcPrice($(this), true)"></td>';
 html +=   '<td><input style="width:50px" type="text" value="'+weight+'" name="weight_impact_'+id+'"></td>';
 html += '</tr>';

 

 return html;
}

 

 

but i dont understand why this variable is not set!!  

 

Can you hel me please?
​Thanks!!
​Regards

one more problem,

make sure your scripts work in the right context (loading product or other object)

 

it will show the same error,

 

when you just  /admin/index.php?controller=AdminAttributeGenerator&token=28a5934743536e3f1xxx

 

it's the right url with product id

 

index.php?controller=AdminAttributeGenerator&id_product=1000&attributegenerator&token=28a5934743536e3f11a323021fcexxx
