I found what was wrong!
put it back to local filterIndex = value - 1; , but the same message came again. i suddenly thought abput the name i gave to the filter module. I changed it and everything worked well! i maybe got the issue because i left a space in "MAIN FILTER".

I'm so glad to see this filter behaving like i want it to do so. Thank you so much for your help, i would probably be mad if you didn't answer to my post :)
