I appreciate your help!
I wish the syntax wasn't that complicated.
People with no background of programming would easily run into this problem. I personally do have a background, but I never learned this syntax.
Thanks a lot!
No problem, I've been trying to rid my scripts from those hidden errors for the last few days, I still think Javascript might have been a better choice to script everything, maybe that will be an option in the future too. Please close the topic if you can, I don't know that page well enough.
