I've created lightbox image galleries for websites before that have all worked perfectly fine however I have now tried to copy and paste the code for a specific gallery into a new HTML file and although the thumnails and larger images work, I can now only click on the left side of each larger image to go to the previous image and cannot click on the right side to go to the next image, despite the fact that the code is exactly the same to the T as the code in another HTML file.
The mouse cursor doesn't even change to indicate the function being there. Not much use only being able to the end of the gallery and then going backwards through the images.
The only time in this gallery the next / right button actually works is from the first image to the second, no further.
Anyone else had this problem or know what might be causing it?
