Problem: I'm trying to increment the value of a variable with the push of a form button. I would like the value to increment by 10 every time I push the button. I'm apparently brain dead today because I can't figure this simple problem out. Please help!
I think we can do this with only a snippet.
my $limit_3 = param("limit_3");
my $limit = param("limit");
my $add_limit = ($limit_3 + $limit);
my $limit = ($limit_3 + 0);
print qq($limit);
<form method="POST" action="add_to_the_number.pl"><input type="hidden"
+ name="limit_3" value="10"><input type="hidden" name="limit" value="$
+limit"><input type="submit" name="action" value="Next"></form>
$limit starts at 0 - Perfect!
One push of the button and $limit = 10. - Perfect again!
Another push of the button and $limit = 20. Again Perfect!
Yet another push of the button and $limit still = 20.
Every subsequent push and the value continues to remain at 20. I would like it to increment by 10 EVERY time I push the button. Where am I failing?
