Hi!
I'm in the process of creating a report in Microsoft Report Services and I have a one problem. My report is to show max, min, avg temperature in specified room. I need to make such a filter values: when I select one value of parameter (e.g. min temperature) must to show this one value in the chart and table, when I select two value (e.g. min and max temperature) must to show this two values etc. On the screen is choice values of parameter "Rodzaj wykresu" http://pl.tinypic.com/view.php?pic=f0x9ad&s=8#.U_o4p2OaKyE . I have a problem with Expression. My parameter have a multiply values and when I write sign "=" is error. I have no idea how this show or hidden values...
This Expression http://i62.tinypic.com/2s6m4o7.png is ok, when in parameter properties is http://pl.tinypic.com/?t=postupload and isn't move when I choice allow multiply values...
