I am opening a Query in Pivotchart View using Command Button, which shows complete Dataset. Current requirement is to filter data on RunTime on Regions (NAE, NAW, EU), how can I pass on Criteria to a Query by selecting a value available in a listbox i.e. NAE, NAW or EU.

I am using Access 2007.

I don't usually use list/check box as a parameter to a query.
In a form, I use the Select dropdown option and source table
in your example are the regions.
For a criteria to a query this is an example I use:
[Enter a 3 UpperCase character].

Hope this helps,
john
