COFUND: What is the difference between the 'Number of person months (employment)' and 'Number of person months (Fellowship)' in Part A of the COFUND proposal template?

The number of researchers is not equal to person months. There is a certain number of researchers, then a researcher will have a fellowship with a certain duration. The duration of the individual fellowship multiplied by the number of researchers will give the number of person months. Example: the duration is 48 months and there are 21 researchers, we multiply and have a total of 1008 person months, and this number multiplied by the unit cost which is 2800 euros in the case of the Doctoral programme gives an EU contribution of 2,8 million euro.
