series data point not matching up with gridline on axis

As you can see on the example this chart isn't matching the data ??? what is going on and how do I fix.

thanks, I like the bar chart.. I actually had to create all the charts from scratch.. but it is killing me not knowing why or what is going on with this one and WHY can't I fix it... lol ... :o) Thanks for the reply, I appreciate you. LaDonna

I can't believe it was that simple of a fix, good grief. Thanks Andy... LaDonna
