How do I fax a signed document

I am trying to fax a transcript request form. When I select the fax option the form is requesting an email address for the recipient. In parenthesis it states that I can use a fax number but when I enter the fax number I get an error stating incorrect email address. The whole reason I opened this account was so I could send faxes since my fax machine was stolen form my storage. The college does not accept email transcript requests and doesn't provide an email to do so.
