change dollars to pounds in packages

[omz1990]

hello, how can i change dollars to pounds in the vshare admin package settings? and how can i enable paypal monthly payment subscription. right now if i enter the number of months for subscription. it calculates the cost of the total number of months. i want it to do enable monthly subscription. can i add the paypal button script somehow that will automatically send the activation to the user when the transaction completes? and i want the currency to be pounds instead of dollars.
