The constant could be within a class or a global, however you prefer. There will be slightly more memory used in a class, but it avoids the constant from conflicting with others in the script possibly. Creating a whole function or class for this does seem a little overkill probably, so a simple global constant should do the job really. Thanks, Ash http://www.ashleysheridan.co.uk
