So I've decided to use PowerPoint with the helpful excel embedded sheets on each slide.

What I want to do is show some of the cells data on the excel chart embedded on the slide of the PowerPoint in a text box.

When I update/edit the cell on the slide in the Excell I need the text box to auto update.
It works with an external Excell file and copy linked picture but not working on the excel file that's within the PowerPoint.

Has anyone any idea.
