object reference not set

[William]

the following code gives a null reference exception object reference not set to the instance of an object.
I have also tried:
TelRpt.ReportParamenters["txtContract"].value = cheader.ContractNum;
gives the same error.
cheader.ContractNum has a value.
If I take out this line the report converst to docx with no problem excet the contract number does not appear.

((TelRptContract)TelRpt).ReportParameters["txtContract"].Value = cheader.ContractNum;

Hello William,

This exception is thrown probably because the ReportParameter is not defined in your report or you have misspelled its name. Please make sure you address the name of the parameter correctly.
