That means that in various calculations (on the indicated lines) you are trying to use a value from a variable that you haven't previously put a value in. This is often indicative of a problem in the logic of your program. -- <http://dave.org.uk> "The first rule of Perl club is you do not talk about Perl club." -- Chip Salzenberg	[reply]

this happens because you haven't assigned any value to $person_count (only to $vision_total). try changing `my ($vision_total,$person_count)=0;` to `my ($vision_total,$person_count)=(0,0);` ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ "one who asks a question is a fool for five minutes; one who does not ask a question remains a fool forever." mk at rio dot pm dot org	[reply] [d/l] [select]
