Set Max for var

[rbettencourt]

I have this gallery, I added a text field which displays the number of items according to the matrix it is in. Currently i am using the 2x6 matrix.

However when the last page is displayed, it goes over the max number, in example (36/32). I want to set the max number to be displayed so that it can look right (32/32). This is my code.

var num = category[currentCategory].matrix.num;
            var from, to, angle, bX, bY;
            // assign new pagecategory[currentCategory].TOTAL
            cPage = page;
            from = cPage * num;  to = cPage * num + num;
            goFull.total.autoSize = TextFieldAutoSize.LEFT;
            goFull.total.text = from + num+"/"+category[currentCategory].TOTAL;

Please help, someone. I can't seem to fix this.
