Sorting of dynamic data feature is not working properly on multiple sortings
I have this page online: http://byzantinoboston.com/BYZANTINO_BOSTON/shop_ethnic_gifts_pottery_glass.php
I need to do the sorting for the data. You can see the menu with different sorting features. Unfortunately, i think i did something wrong and it is working only for one feature, not all of them. if you try to click on different links for example 'the lowest price' the first page loooks ok but the second tand further are a complete mess. I tried to create a new page and followed all the instructions from the tutorial and still have this problem/ Please, help me. Thank you!
