This is not totally PHP but is related. I have a page which works in IE but not in Firefox, the page basically does the following: PHP Script outputs several images onto my page, and each of them have a unique id (from a mysql database) stored in the id tag. I have a javascript function which is called on mouse over of each image. This function gets the value of the id tag and display in a table below my images. In IE, this works, but in Firefox, the data isn't displayed in the table when I hover over the images. I'm guessing one of the features i'm using is not compatible with Firefox, can anyone tell me what it is and how I can overcome it. Thanks in advance Regards Jug
