Help with expression inside multibox

Tue, 12 Jun 2012 06:36:07 GMT

Hi,

This might sound simple but am really not able to find a solution for this till now.

I need to have a multibox that will show year,quarter,month and week. In each drop down (for each of the mentioned items), i need only those values for which the count of survey_id is greater than one.

making it more clear, lets take the example of year. year is being taken from a calender table that has years ranging from 1800 to 2500.

I just need those years for which the corresponding count of survey_id is >0, to be shown in the drop down.

can anyone helpme frame the expression that will mean.. show only those years in 'year' drop down, for which the corresponding count(survey_id)>0

something like =if( (count{<Year>}(survey_id))>0, Year)

however the above expression returns no values.

plz help

thanks,

vishnu

you can use

aggr(if(count(survey_id)>0,Year),Year)

Change the expression like

count({<Year>}(if(survey_id>0, Year)))
