Im searching the way to found the sum of filesize uploaded with blueimp .

I try this :

2. <script>
3. var sizetotal=0;
4. $('#fileupload').fileupload({    
5.     complete: function (e, data) {
6.       $.each(data.files, function (index, file) {
7.             sizetotal=sizetotal + file.size;
8.       });
9.        
10.       
11.     }
12. });
13. console.log(sizetotal+'|');
14. </script>

But in console i have :

jquery.js:358 Uncaught TypeError: Cannot read property 'length' of undefined(…)

The row  is this :

2. each: function( obj, callback, args ) {
3. var value,
4. i = 0,
5. length = obj.length,     // error in this point 
6. isArray = isArraylike( obj );

Can u help me ? Tank's
