Ozark Trail Pop Up Canopy Side Walls

Hello all - so I have a 10x10 canopy from Ozark Trail - the ones they sell at wal-mart - and need to get some side walls. I have the tan color and while it appears wal-mart sells this color pop-up, it does not sell the matching side walls. I am having issues tracking these down. Anyone have any luck with these - or even another brand that will work that I could look into?

Thanks

Bingo!
