Thank you so much for trying to help me. I'm new to Jaspersoft and struggling with print this in percentage form. $V{v-beginning-stu-cnt} == 0 ? 0 : $V{v-beg-atristk-cnt}/$V{v-beginnin-stu-cnt} I tried to cast v-beginning-stu-cnt to java.lang.Double it gives me compilation errors. So, how can I change these variable to be decimal numbers? Also, I display these variables and I don't want to display them on my report as a decimal number. Do you have any other ideas, and if so please explain to me what to do in details, as I told you I'm really new at this. Thanks...
