Error in source code

Hi, checking the code of my webpage (view-source:http://www.cajas-empaques.com/)
i find out that the line 283 is marked in red and it says that theres several opening tags missing (a, ul, li), this seems trange for me since in the line 277 theres a very similar code that doesnt show an error, can you help me to fix this? i dont want any error in my source code, thanks in advance
