End your code with:

This.SelStart = len(trim(This.Value))

For other ways of getting the cursor at the end of a textbox's value, you have to set SelectOnEntry to .F., and you can not have K in the Format property. To handle cursor placement if a user TABs into the field, in the GotFocus put the following code:

DoDefault() && to run any code in the parent -- this is optional
This.SelStart = len(trim(This.Value))

If you want the cursor at the end if the user clicks in the text box, also put the code in the Click of the textbox.
