I called ashworth you have to call the school give your ID number and your birthday chose option 1 then option 2 they will set you put with a tutor but it can take up to 24 hours for someone to call you back!
A tutor called me back this morning. She is going to email me a easier formula for conversions. When I get it I will post it. It is alot easier than the ones in the book. She also said that the techs will not have to use them while on the job. That all doses are alrady converted and the ones that arent the pharmacist will do.
