Thank you very much, that solved my misery :) Gan

Hi, Instead of trying to calculate the "y" position, you can set sub-reports with the Position Type to "Float", flag the "Remove line when blank" and set up a "Print when expression" that evaluate the choosed options. I work with IReport though, so I can't be really precise on how to implement it into your application. I hope it sends you into the right track. Gan

I am trying to build a report with running percentage. A "sum" variable evaluated "now" will effectively calculate a running sum of a field. The same variable, evaluated "report" will provide the total sum. How can I divide the running sum with the total sum, i.e. calculate and display the running percentage? I am including an example report.

Yes, it is "sum" and F$ I've attached an example report, give it a look. [file name=RunPerc.jrxml size=11917]http://www.jasperforge.org/components/com_joomlaboard/uploaded/files/RunPerc.jrxml[/file]

Well, I would have expected a total for the column, not the double of the current line. The tricky point with running percentage is that I need the same "sum" variable computed twice: "now" and "report". The first instance will return the running sum, the second the total sum. I still don't have a solution for it.

Does not work. I tried to display the variable on a dedicated textfield to verify its behaviour, what I get is the double of the field value. The textfield is evaluated "now", the variable is reset to "none". :S

Schaibaa, I agree on the fact that texfields and variables are different entities. The point is that the variable is the same (a "sum" variable on a field), just evaluated (computed) at different times: "now" for running sum, "report" for total. To my knowledge, "evaluation time" can be done only with textfield, so here is where I am stuck, since I can't choose two different evaluation time for the same variable, in a formula. But maybe I am on a wrong track and there is a different solution for my running percentage request. I just can't figure it out right now...

I am trying to do a report with running sums and percentage. Using a "sum" variable and a textfield with evaluation time "now" I can have a running sum. A second textfield, eventually hidden, with evaluation time "report" would provide the total sum to each line of the report. Last step, where I'm stuck, would be to set a textfield with evaluation time "now", that divide the running sum variable with the content of the hidden field (total sum). How can I retrieve the content of a textfield from another one? The report would look like something like: Item Val RunSum RunPerc ----- --- ------ ------- Item1 10 10 25% Item2 10 20 50% Item3 20 40 100% ----- --- ------ ------- Thanks in advance to all contributors.
