Changing the number of attemps in question bank by coding or by using variable

Hi!

I'm doing a cleaning operation on one of my first storyline project.

In this one I use questions banks and "lonely" questions.

I would like to change the number of attemps to answer to questions by using a jsp code for instance or a . Actualy, i have 2 banks with the same questions, one bank for 1 attemp and another one for 2 attemps. My goal is to assemble in only one, this 2 banks and with a small jsp code or another tip change the number of attemps for each contest.

Hope someone had a solution.
