New to paypal. need help

well, i made a paypall a few months ago but never really needed it up untill last week. i loaded some money onto the account via moneypack cards and was ready to complete my order when i noticed that theirs no option to pay with the money thats loaded onto my account. only the option to pay with a credit card. any way i could use the money on the acccount, or am i just missing something.
