New tab not staying selected

[invitezone]

I wonder if someone can give me some help on my tabs.
I am sure your sick of tbs questions by now by reading some of the above responces to your help, but im really stuck with this.
I am a total n00b with Vbulletin so I cannot make sense of the advice you are giving above, so please if you can be clear with me

any here are some screens of the tabs I have created.






Now as you can see I have the tabs working, but as also im sure you will see straight away, my tabs wont be highlighted after I click them.
I know from reading above that I may need to create plugins or something and do something with This_Script, but I dont really know what these things are or how to do them.

I know I ask a lot but this is so frustrating. I would really appreciate anyone taking the time to write a simple step by step set of instructions for me to follow.
Hopefully it will help others with their problems as well as me.

Thank you to whoever tries to help me.
