Js - adding to a select listbox

[alex_read]

last huge problem then this project's finished thank god !

I have 2 <select> tags acting like vb listboxes on a web page. When a button's clicked, an entry (<option> tag) is taken out of the left select & put into the right select box.

The problem is if you hold shift & multi - select entries. If these multiple entries are next to one another, they don't all copy over. If they aren't next to each other, then they all do copy over & I'm stumped becaus of this.

Hopefully this code (not too big) should help & I've written some comments in to expain this better.

Thanks All !
