Problem with query and parameters (D3 + IB + Zeos)

[klandestyno]

Hello people ..
I have a problem using parameters.
I am using Delphi 3 Standard with Zeos 5.4.1 Component and Firebird Database.

The code:
*****************************************
With TZIbSqlQuery Do
Begin
Close;
ParambyName('Name').AsString:= 'Value';
Open;
End;
*****************************************

The message error:

*****************************************
Parameter 'Name' not found
*****************************************

The ParamCheck property is False. This code found with IBDataSet component .. and others component, but I need to run whith Zeos.


Can anybody help-me?
Thanks
