How do I access variables through code?

[EDV Gradl]

When I do:

report.Load("Variables.mrt");
report.Compile();
report["VariableName"] = "Value";

I get an error, Field VariableName not found, but the variable exist. So how Do I acces it? Or can I get a list of all variables in the report via code?

Thanks!

Check Property ReadOnly of VariableName is set in false in Report.

That did the trick. Thanks!
