Sorry,
I am still stuggling on formating some of the suttle details with CSS.
Firebug helps me on most of it but it will doesn't point out to me a few of the more suttle things ... at least I think they are.

Could someone please tell me how to edit the text located withint the red box I drew on the attached image.
I would greatly appriciate it as I'm tired of feeling stupid for the past 2 hours tonight with no luck.

You will find this text in one of the files in Checkout/PaymentForms folder. Open and edit the text in the corresponding file.

You need to edit Website/Checkout/PaymentForms/MailPaymentForm.ascx and manually change text in that file.

Thank you so very much.
No wonder why I could not find it.
I was looking under the CheckPaymentForm.ascx

Thanks for your help.
Tom
