You have to transfer funds into your paypal account which will take about a week, unless we're talking a debit/credit card which will take confirmation that you legitimately have access to it- then transferring is instantaneous. If it's straight up debit, as in not also a visa or mastercard, you might want to ask their bank if you can and/or how to transfer money between them and paypal because for some reason my bank won't let paypal take money from my account even though they they have my secure transfer numbers and everything.
