I need to add extra persons of interest to an appointment. I tried several things, but they are not satisfactory. Then I tried to add a buttton, connected to a link, and I tried a button to use php. Both buttons do appear in the menuitem Toolbar, but if you assign them into an area (i.e. besides the exit button) it does not show up.
No announcement yet.
[SOLVED]Adding buttons to calender application does not work
