Links from Excel to PowerPoint break

[arren_excel]

Hi everyone,

I am having some trouble regarding linked charts copied from Excel into PowerPoint.

I am working on a powerpoint template, with several charts created in a separate excel file (located in the same folder). I want to be able to update the excel file, and for the powerpoint to update the numbers (automatically or by clicking Edit data). Often, but not always, when I open up the template with a few days apart the links are broken and I receive the below error.
"The linked file isn't available. This error can occur if the linked file has been moved or hasn't been saved. embedding the data instead of linking it can help avoid this error, but the data won't be updated automatically if it changes in the source file"

Is there any way to avoid this from happening? It is likely something i do that cause this. I find it strange that it affects some charts and not others.

I keep the excel powerpoint file in the same folder at all times.

Is there any further information I can provide that makes it easier to understand my problem?

Any help would be greatly appreciated.

Thanks

Arren
