try:
reportContext.getPageVariable("V_REP_VAR");
to access the report level variables. global and globalpersistent
variables are a way to store variables for access in script and
expressions. persistent means it will write the value to a rptdocument
to store the value across phases (run then render). Report Variables
can be used in similar fashion but were primarily designed to be used in
autotext elements on the master page (eg page n of m).
