How to debug the error?

[Vancylynn]

Hi anyone can help me to debug the error? I have tried for few weeks but notable to figure out why.
The function of macro in this file is used to copy the chart from excel to presentation slides. I saved the presentation slides template at desktop and copy the link to the excel macro file.
When running the 1st time macro, it's able to works well. After close the presentation file and re-run again the macro, the error message prompted said run time error. I have no idea how to debug the error. Hope anyone can help me?
