Hi Gurus, Here's the story. I've done a JavaScript and now struggle to integrate it into the WP Admin interface. Where you add a new post, there is a certain custom field and what I need is a button near this custom field. Click the button and a pop-up appears. It is like a pre-selector, like all those clever calenders. My JavaScript works perfectly if tested outside WP. Now, if I add it to the admin php script, it does nothing. If you have had experience in integrating things into WordPress, please give me your best quote. I know it is not a big job. It must be something I'm missing. Payment through PayPal only.
