How can you delete CR parameters from VFP

[INFORMAT]

Hello

I'm a Visual Foxpro programmer and I use Cystal reports .

I have a CR report with 4 parameters.
On my form in Visual Foxpro I place an OLE control that send these 4 parameters to crystal reports.
I use the following code to fill the parameter fields:

THISFORM.OleControl1.ParameterFields(0) = ...
THISFORM.OleControl1.ParameterFields(1) = ...
THISFORM.OleControl1.ParameterFields(2) = ...
THISFORM.OleControl1.ParameterFields(3) = ...

Then I print my report and after this report I want to print directly an other report that have no parameters.
How can I delete the 4 parameters that I have created with my first report. If I don't delete these parameters, they are used for my second report and these report doesn't allow parameters and the I receive the CR error 20553 that means that I use invalid parameters.

Thanks for your time and answer
