                                            | hello,I have built a report using the matrix wizardon the left I have a name the columns are created based on date and I am doing a count on a number field.example:names     2013    2012    name1     500     400name2     100     300name3     100     100what I want to do is calculate the difference between the 2013 and 2012 column but this seems impossible. The table would look like this:names    2013    2012  Differencename1    500     400   100name2    100     300   (200)name3    100     100    0how can I calculate the 2013 and 2012 column in report builder?  there is only one field that I put in the column groups which groups the column into year. Any help would be appreciated.Thanks |
