This is the error I am receiving. The drPMRLog is returning a new row, with the columns, except for the PK that has iterated, set to NULL.

Line 196: this.oPMRLog.NewRow();
Line 197: DataRow drPmrLog = this.oPMRLog.DataRow;
Line 198: drPMRLog["Title"] = VFPToolkit.strings.AllTrim(this.cboPosition.SelectedItem.Text);
Line 199: drPMRLog["Biz_Unit"] = VFPToolkit.strings.AllTrim(this.cboBizUnit.SelectedItem.Text);
Line 200: drPMRLog["Program"] = VFPToolkit.strings.AllTrim(this.cboPosition.SelectedItem.Text);

The data from the combo box, when viewed in the debugger is returning the proper value (Not NULL), with the same exception listed below.

"[NullReferenceException: Object reference not set to an instance of an object.]"
