Howdy all,

Does anyone know of a script to add days to a date? For example, in textbox1, I have date value (say - 7/1/2005). In textbox2, I want that date plus seven days to be displayed (7/8/2005) (textbox1 will be different depending on when the user opens the form). I can't seem to figure this one out for the life of me...
