More form problems for a novice

Hi.

I am trying to declare the variables for all of the headings within my form, however I am getting the following error:

Error Type:
Microsoft VBScript compilation (0x800A0401)
Expected end of statement
/example/Bookings_process.asp, line 15, column 124
Dim Firstname, Secondname, Organisation, Position, Address_1, Address_2, Address_3, Postcode, Telephone, Fax, Mobile, Web, E-Mail, Request, Service, Therapies, Events, Training, Comments, theDate,sql

I have successfully tried the tutorial using just 3 fields but obviously I need to have all of the fields available form my form to work, can you advise what I should have addeed>

Regards,

you can't use "E-Mail" as a variable name....  keep it to letters, numbers, and the underscore character

that's why that error gets thrown
