Build a Website !

i was trying to cover my adds by putting div on it , but now i don't know what is happening . adds are showing but when we click on it it show nothing , and the div i put on it is not visible , resolve this bug . check it by yourself ([login to view URL]), click the top most add , i put div on it , check it what error it shows when you click the top add. and then bid . looking forward for your bid .
