addItem永远不会递增，因为初始值为0并且您已检查该值是否大于0.删除if条件。


其次，removeItem被注释掉了。

是的我有很多东西被注释掉了我只想增加它并留下它起来。就像一个柜台。但是我有增加的问题，并使其保持其价值。帮助！

I have this code I would like to use as a link counter but it just will not store the number nor increment it. please help. I need this ASAP.

addItem can never increment because the initial value is 0 and you''ve got a check that the value is greater than 0. Remove the if-condition.

Secondly, removeItem is commented out.

Yes I have many things commented out I just want to increment and for it to stay up. Just as a counter. But I have problems incrementing and making it hold its value. help!
