jQuery Forum

But we can't tell from your header information what you actually have on your server, whether you have error messages on the Javascript console, what the differences are between your "test program" and "live program" or whether all the needed files are in fact present, or might be corrupted.

First step is to look for error messages in the Javascript console of any desktop browser.

Why are you using such an old JQUI library? Are you updating an old site? Did it once work, and stopped working correctly at some point? If so, when? What changed?

Many thanks watusiware.

I checked the console output on my browser debugger but found no errors.

Then I updated the script to call jQuery UI 1.12.1

As I was updating the main programme I realised that I had omitted a call to jquery.ui.combify.css (it was in the test programme).

after adding the link to the main programme it worked fine.

Thanks once again for your good advice.

Just one otheer question: what is the point of calling:

??

Thank you
