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?
