Python doesn't allow you to rebind a variable from an outer scope in an inner scope (except for the special case where you explicitly use the 'global' directive, which is no use for the nested scopes you are using here). So when you assign an identifier in a function Python assumes that you want that identifier to be a completely new local variable, *not* a reference to the variable in the outer scope. By writing 'fields= ...' in cutbits you are telling Python that fields is now a local variable to cutbits. So when the function is entered, fields is a new variable with no value yet, and when you first try to read it without writing to it first you'll get an error. What you probably want to do is keep 'fields' pointing to the same list, but just change the contents of the list. So replace the assign operation with a slicing one: del fields[:widths[i]] -- Andrew Clover mailto:[EMAIL PROTECTED] http://www.doxdesk.com/ -- http://mail.python.org/mailman/listinfo/python-list
