Parameters collection

I have a function defined in Report->Report Properties-> Code Tab which
I want to access the parameters collection to look for a Debug flag.

I get the following error:
c:\Reports\ReportMockup.rdl There is an error on line 4 of custom code:
[BC30469] Reference to a non-shared member requires an object
reference.

How do I access the Parameters collection within my custom code?

Ideas anyone?|||Try...
report.Parameters!parameter_name.Value
Thanks Tomson McCabe :)
