System Error: Object reference not set to an instance of an object I have spent hours creating a chart 10 x 10 inches only to get this message when I try to turn it into a pdf. This is not the first time how do I overcome this please?
It sounds like the problem is there since this not the first time.
The normal way to create a PDF is to "print" it to a virtual printer that is a PDF creator. I normally use Foxit (Adobe clone) which has such a printer as part of the product. Adobe is similar.
