Cascading Parameters problem

Are there any way to update parameter values first after a several Cascading Parameters (text fileds) is set?

Ex:
First I would like to fill the parameter fields (text fields):
From Date - To Date,
From Customer - To Customer

then the process begins to filter the rest of the fields values.

ChristoferYou could put the fields that you want filtered by the Date and Customer into a subreport then filter the subreport by the value in the Date and Customer fields.
