Lab 1b

So It seems like I had did something wrong in this lab starting at step 20-36, In order for me to fix this problem i have to abondon my account and make a new one and rebuy the package. One I dont have that type of money to be spending for this. two, I like my score but it says it would affect me in lab 2a and i was wondering how bad would that be. Three, IF i did go back to do steps 20-36 again would i have to do the whole assignment over ?
