Hello mr_mischief,

Wow I had no clue about all this interesting solutions that you proposed. Yo be honest I want to do something so simple but it has ended up being so difficult. I think that I am on the correct way though I thought about it and maybe there is a solution to my problem. Well I might need some time to implement it, because I am not an expert in programming but I will get there I think. :D

Thank you for your time and effort to assist me.
