Constantly having problems loading code

every time I go to enter html into my shop or petpage I also get an error dealing with the tags or brackets and can never figure out what's wrong for example when I enter my counter code in the beginning tag is always flagged as incorrect... anyone know why?

There is a coding glitch, TNT knows about it and they will probably start fixing it on Monday. *** [size=10]Grooming, wearables, backgrounds, clothes, Fire & Air Faerie Quest items! http://www.neopets.com/browseshop.phtml?owner=nioe_yemar&misc Owner of The Rainbow Fields Mall & Celestial Colours Guild![/size]

There has been a thread discussing this, if you are interested. http://www.neomallers.com/node/1713
