can anyone help me with this?

hi everyone!

Please help me with this...I'm trying to create a relation (master/detail) and got a code from MSDN. When I ran the program, this error appeared:

An unhandled exception of type 'System.NullReferenceException' occurred in Quote.exe

Additional information: Object reference not set to an instance of an object.

This highlights my code in declaring the relationship...
ds.Relations.Add("DocTran", ds.Tables!Qoutedoc.Columns!Reference, ds.Tables!QuoteTran.Columns!Reference)

What's wrong with my code? What did i miss out? Please help me! Thanks in advance.

did you instantiate your dataset?

dim ds as new DataSet()

It is nearly an impossible task to help you "Fix your code" without being able to see it. Please post your code and we can probably take a peek and see what's wrong
