I have data that is loaded into the system from a 3rd party data set, they have a reference number which can be added against more than one line of data.
I need to count the number of times the field is populated with the same data and display it on that rows form display.
Example:
I have 3 rows of data the field called Reference shows as 12345a in 2 rows of data and 12345b in the third row.
I need a field to display the total count of all rows that match that fields reference code against each row
so the field on both rows with 12345a will show as "2" and the row with the reference set as 12345b will show "1" in the count field.
I need to do this using a workflow or rollup/calculated field. i cant use a plug in.
Any help much appreciated.
Thank you
Colin
