I have a table with 3 columns. The firs colum lists a bunch of info along with a checkbox next to each item. The second column lists a form button "Add" and the third column lists a select box.

I want to be able to click a checkbox next to one of the items, click the add button, and whatever I clicked on show up in the select box. There is a search field also where people can search for info, and the select box need to be able to retain what the person checked previously. For example:
I search for an item, check it, it adds it to the select box. Then I search for another item, and it displays the results again, only this time the select box already has 1 item in it, which I selected previously.

If anyone can help, it would be greatly appreciated!!!!!!!!!

1) Use javascript to add checked items to the select box.
2) If "search" is pressed, have a javascript function set all the elements in the select box to "selected" (so that they will be submitted with the post) and then submit the form.
3) Have the form processing script store the select box values in an array.
4) Perform the search.
5) Output the search resulsts and a new select box (pre-populated with the stored array values from the previous form).

Could this be done without using any javascript? An example of something would be greatly appreciated.

The problem with not using any javascript is the second select box. If you create a form with a select box and somebody presses SUBMIT, only the values of the select box that are SELECTED will be returned to your script. In order to rebuild the select box (with the values they already added) for the next display, you need to use javascript to select all the values (you did define the box as "MULTIPLE" didn't you?).

Even if you build the select box all the options SELECTED, one click from the user and they will have deselected something or everything.
