Can't display secondary category axis labels in Report Builder 2.0.

Question

Most property settings are the same for the primary and secondary category axes. Interval: Interval=1, IntervalType=Months. Labels: HideLabels=False.

However, Scale maximum and minimums are different:

Primary: Maximum=Parameters!EndDate.Value

Primary: Minimum=Parameters!StartDate.Value

Secondary: Maximum= IIf( Parameters!StartDateB.Value Is Nothing, Parameters!EndDate.Value, DateAdd("d", DateDiff("d", Parameters!StartDate.Value , Parameters!EndDate.Value ), Parameters!StartDateB.Value ) )

Secondary: Minimum= IIf( Parameters!StartDateB.Value Is Nothing, Parameters!StartDate.Value , Parameters!StartDateB.Value )

The primary axis labels display and secondary labels do not. Any suggestions?

Thanks, Hank
