Intead of in slider scripts, making use of the USE function I simply just added in a RUN script function also and the door instantly opened. Basically the door combo script wasn't running at all. So what this means is the door combo script was dead till I had a run fuction added in to process and register each command as it played.
Thanks to no one for the help.
At least someone tried to help recently via a friend contacting someone else for me. If I had a quote from darkboy I would of quoted him also but this guy was contacted first. Guess the community isn't completely dead.
