Need help with Scar.

Hello everyone, I have a problem with scar. Everytime i try to make a script work, i target the runescape screen, and click play, Nothing happens.
Is there something im doing wrong? ive tried it with 3 different scripts and none of them work, Is there a reason or is it because my laptop is being a dick?


Thanks.

 

I would be able to help you if you pastebin or post the script(In code tags).
