parameter in conditional style in crosstab

[mvb]

 I'd like to use a parameter in a conditional style that I use in a crosstab, but it doesn't seem possible: the compiler gives me a message 'Parameter not found'.  I can't seem to access any self defined parameters in a conditional style that I use in a crosstab.  It doesn't matter if I define the parameter at the top level (report level) or the crosstab level.  What am I doing wrong?

 

This is the expression I'm using in a conditional style:

new Boolean($V{TOTMeasure}.intValue()>=$P{G_LIMIT1}.intValue())

The parameter G_LIMIT1 is defined at the report level and the type is java.lang.Number

I'm using the conditional style in a crosstab on the detail field.

First I thought that probably parameters on a report level aren't accessible within the crosstab.  But even when I define the parameter within the crosstab it still won't compile.
