So I have a list of "record companies" each having their IDs (1, 2, 3.....)
And when clicking on all of the companies they work fine when there are no products associated with them (brings results page saying that no product is there)

however, i started adding music products and selecting the appropirate record company, however, some of the links break after i do that (not all, but select few!)

Any suggestion as to why this is happening? If you need a link to my site or other information please let me know!

your feedback is much appreciated
thank you!
