So I don't understand why I have an error with this code:

var
CurrentParam : TParam;
FQuery : TIBOQuery;
Begin
CurrentParam := FQuery.ParamByName('p' + CurrentField.FName);


It retrun this error:
[Error] MyFile.pas(453): Incompatible Types : 'TParam' et 'TIB_Column'

But when I was using a TQuery it was working fine...

So did I do something wrong?

Thanks
