I am trying to show/hide a control based on selections from a drop down list. Documents Drop down has 4 options - A, B, C, D and I need the control to show when either A or B is selected. I got it to work for A but when I add B using the OR (||) notation in my expression, form does not display at all. Please does anyone have ideas or alternative suggestions?
Expression reads thus:
Documents!= ("A" || "B")
Documents!="A" || Documents!="B"
