Michel, if you have declared a report variable with the name 'pMyVar' in the report, then this will be private variable. If you wish to use a public variable in a report, do NOT declare it in the report - just use it as you would in a PRG.
Also, add this variable to your detail, page footer, etc. and watch to see where it changes.
