he meant only that i have to change the var. nothing more... but i´ve changed the thishome var. and the mistake were already there .. so i had deleted it. The mistake were that i didn´t said file-> save as ... i had clocked on it and then save as ... and so i had some html codes in it. Now i´ve downloaded again wighout html codes but the 500er is already there (the new file oly changed var.)
