Unless there is an input mask - this would be an redundant check. The highlighting would only occur to the extent there is something in the text box. If nothing is in the textbox - and no inputmask exists - no hightlight will occur - obviating the need for the If...Endif. Of course, all of this is moot if K is assigned to the Format Property.
