I have one interactive grid and i want to sum the amount at bottom, i have created aggregate on report but the values are not changing in the interactive grid, how to get total sum of Interactive Grid Amount Column values

You could create a dynamic action on the Interactive Grid region.
True action will then be:
That's it - run the page, change some value, push the "Save" button - the total value should now change.
