So what you are telling Python to do is to split the beginning from itself, or to insert a blank so that it is split. Also, you shouldn't use "input" as a variable name since it is a built- in variable. One hack to make it work is to add the following line right before you print "projectOptions": projectOptions.pop(0) # pop the first element out of the list Mike -- http://mail.python.org/mailman/listinfo/python-list
