Pass Vb global variable to CR

I have a global variable that I want to use in all my CRs, its set when my main menu opens, works quite well and I have it as a title on all my forms. It is layed out like this. strTitle
ACME Housing Development
123 Any street
Some City, State, Zip
Phone 555-555-1212, Fax: 555-555-1313
John Doe Executive Director

Anyway I want to use that for the title of all my reports but I'm having trouble comprehending how to pass the variable to my report viewer and onto my report.
I've found a couple examples, and can't seem to get any of them to work.

If someone has a short example of how to pass the variable that would be great.

Thanks
