What's wrong friendster

I am done with my heavy midnight snack hehehe.. Since no fishes to catch I opted to visit my friedster account. Approve some pending comments and after I tried to send some f my friend a mother's day greetings and i want it to put a greeting card. But for heaven sake I can send it when i am done. I always recieved this error "The HTML you entered is invalid". I don't know what is wrong actually since i know i copied the code correctly.
