HListQueryParameter

Webdev12 - Reports and Queries

Trying to show param1 and 2 on preview of report and trying to use online help example routine below:
-------------------------------------------------------------------------
// Retrieve the parameters of the CustomerZip query
ParamList is string
ParamList = HListQueryParameter(S_44Powers_v3_Rep)

// Adds the list of parameters to COMBOBOX1
ListAdd(COMBO1, ParamList)

--------------------------------------------------------------------
I tried the above example routine but gives error:

Error at line 4 of Pre-Print of STATIC24 process.
HListQueryParameter function called.
S_44Powers_v3_Rep object not found.


Report query is called S_44Powers_v3_Rep so what am I doing wrong?

Thanks in advance
