I have looked a the code that displays the course summery but I am afraid its beyond my ability with php.
There is a bit going on there and it seems as though the front page, when the site id and the description id are the same its a special case, perhaps it jumps out before it gets translated by format string().
If anyone can shed a bit of light on this I would be grateful. Perhaps show me the proper syntax for trying to use the format string() on the variable $COURSE. That might do it??
