Say I have a Service Type called '20Hr Plus' and a rate type called 20
Hours.  This Service Type allows the users 20 hours online for say $9.95
plus has an added charge of $1.25 per hour for over 20 hours.  I put the
$9.95 in the Cost field in Service types for '20hr Plus'.  
Is it correct to put $0.00 for Regular Cost and $1.25 for Over Charge with
the Hours set to 20 and set Allow Overtime to On?
Also, please define the function of the Charge Primary check box.  
Thank you.
