i have create a dashboard prompt for a year number. i placed 2 reports on dashboard (Year / LastYear). the first with the value of the prompt,
the second must be calculated the value of the prompt -1. (Year = 2008 -1 = 2007).
the presentation variable is @{VAR_JAHR}, Prompt Value is 2008
i have create a controllfield, in formular editor. the formula *@{VAR_JAHR} -1* is 2007, that is ok.
in the second report i set the filter at the presentation variable @{VAR_JAHR} -1 or @{VAR_JAHR-1} ..., but this is a error.
