Unfortunately I cam not sure where I can place them as the 'opacuserjs' only accepts javascript embedded in:
$(document).ready(function(){});
That isn't true. The opacuserjs preference accepts any kind of inline JavaScript you want to put in it. Anything which would normally be included inside <script> tags on your page.
Below I have posted the two functions. Do i have to create a separate javascript file and reference it or can the fuctions be editted to work in 'opacuserjs'?
No, you can embed this code in opacuserjs. But it looks to me like the code is intended to work with an onclick event attached to an element on the page. What is the script intended to do? Do you have a working example outside of Koha? -- Owen -- Web Developer Athens County Public Libraries http://www.myacpl.org
