Is your VFPToolkit object in scope and instantiated?

btw, you may bypass the use of the VFPToolkit and still trim your combo value by using;
     this.cboBizUnit.SelectedItem.Text.ToString().Trim();
>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 198: drPMRLog["Title"] = VFPToolkit.strings.AllTrim(this.cboPosition.SelectedItem.Text);

>Line 200: drPMRLog["Program"] = VFPToolkit.strings.AllTrim(this.cboPosition.SelectedItem.Text);
