i dont know where to put the colspan attribute

Replace this line with your code. 

<th colspan="3">3 columns across!</th>


#2

at the element you want to span multiply columns, in this case:

<th>Famous Monsters by Birth Year</th>

also, you only have 2 columns, not three, the exercise is testing you


#3
