I have a form, and in this form, there are 2 drop down menu, and a text box ,two buttons (labelled "add" and "remove") and finally, a listbox.
The question is, when the user clicks on the add button, how do I add the value selected in the drop down list and text bopx value and put it into the listbox? After adding to the listbox, the selected value needs to stay in the drop down menu and not get removed. When the remove button is pressed, the selected value from the listbox just needs to disappear from the listbox and not the drop down menu.
Thanks in advance
