David:

If I want to display the exception in a message box, don' t I trap it 
like this?

try {
   decimal aValue = Decimal.Parse(TextBox3.Text);
   TextBox3.Text = System.String.Format("{0:C2}", aValue);
}
  catch (FormatException e) {
  MessageBox.Show("Error: "+e, "Error Formatting Total",
				 System.Windows.Forms.MessageBoxButtons.OK, MessageBoxIcon.Asterisk);

}

I get the following error:

[C# Error] FrmPOS.cs(597): A local variable named 'e' cannot be declared 
in this scope because it would give a different meaning to 'e', which is 
already used in a 'parent or current' scope to denote something else

TIA
