'''Field to count''': ''Typically, this will be a list type field, but this is not compulsory. The data in any field can be parsed using any chosen delimiter''
 
 
 
'''Delimiter to use''': ''This is optional. If not specified, the function will default to using a semi-colon delimiter. Anything can be specified as a delimiter, from a single character to a whole word or words.''

''No delimiter has been specified here, therefore the function will default to using a semi-colon. The result here will match the number of people shown in a properly tagged photo. Note that the function is smart, so, if a file has no [People] tag, the function will return zero (0), and if it has [People] data, but no semi-colon, the function will return one (1).''
