Object Reference Error filling a datarow

This is the code:
Dim dr() As DataRow = DataSet.Tables("TableName").Select("EVENTNAME = '" & name & "'")
I get an "Object reference not set to an instance of an object." Error when this line is executed. It is looping through a list of selected items in a listbox. I think it has to do with how I have the datarow declared because I can look at the name and I see it ok and I also do a null check on the name before I use it.
Visual Studio 2008, VB.NET. Any ideas?
Yep it was a wrong table name. I guess after looking at the code for 8 hours that minor detail I just wasn't thinking to check. Thanks!

You probably have the wrong "TableName"
.

For me it looks like it is the select statement:
vm_DataTable_SELECT_string = "[MyField] = '" + vm_TEXT_string + "'"; DataRow[] o_DataRow_ARRAY_Found = vco_DataTable.Select (vm_DataTable_SELECT_string);
