Question : Crystal Reports Record Selection Formula Based on Two Date Fields

Hello Experts,

I am working on a report (Crystal Reports version 11), that uses a global date parameter to link multiple subreports.  When I run the report I enter a single date range and each subreport has the following in its record selection:
{MManpower.M_tTime} >= {?Pm-@Begin Range} and
{MManpower.M_tTime} <= {?Pm-@End Range}

My quandary is that I am trying to add a second date condition in the record selection using the following syntax:
(({MManpower.M_tTime} >= {?Pm-@Begin Range} and
{MManpower.M_tTime} <= {?Pm-@End Range})
or
({IIncident.I_tTimeTransmit} >= {?Pm-@Begin Range} and
{IIncident.I_tTimeTransmit} <= {?Pm-@End Range}))

But, I am not getting records back that are based on the second table.date field - I am only getting records back based on the first table.field.  Is this because the subreport link in the primary report is based on only the first table.field?  If so, is there a way to link the global date parameter in the subreport links to more than one table.field?  Or, is my syntax incorrect? Or do I need a different work-around?

Thank you for your help with this.

Answer : Crystal Reports Record Selection Formula Based on Two Date Fields

Do you need OR, or AND as the operator here?

Do both date conditions need to be met in the subreport(only) OR both ?

(({MManpower.M_tTime} >= {?Pm-@Begin Range} and
{MManpower.M_tTime} <= {?Pm-@End Range})
or
({IIncident.I_tTimeTransmit} >= {?Pm-@Begin Range} and
{IIncident.I_tTimeTransmit} <= {?Pm-@End Range}))
