Database issues

[thaimann]

On Delphi, I normally create a Database Form.  This is where all of myTDatabase objects (TDatabase, TDataset & TDatasource) and procedures are kept.  Then when I want to open a dataset or refer to a dataset, I refer to that form.  With Lazarus, it doesn't seem to allow me to refer to a TDatasource which is on a diffrent form (I have added a "uses databaseunit").

My project is compiling, but when it executes it is saying "ClassTDataSource Not Found" and then the program ends.  What is wrong here? Do I need to add something to my users path? Thx,    Terry
