How to solve custom view point problem?

customer view points (for example: simplepoint) will conflict between different pages. If you open customViewExample1.jsp and then open customViewExample2.jsp, the value displayed on customViewExample1.jsp will changed when customViewExample2.jsp is opened. simplepoint or script point value always show the point value of the lastest opened page. Because each page’s point id use same id start from “0”, for example: id=“c0” etc. like from c0~c99, and when you open another page, id still start from “c0”, so they conflict each other, how to solve it?
