Well, it can be hard to deal with multiple scripts, but send me the Skill Shop script and I will see if I can work it out. Generally, incompatibility issues occur when one script (or both) alters a default class that the other relies on, so I will see what default scripts that one modifies or relies on, and I will try to make it independent, i.e. alter it so that it no longer relies on any default classes. If it is too integrated into the default scripts, then I may just write the script from scratch with the same layout and options in order to decrease dependency (with credit to SephirothSpawn of course)>
Either way, you can PM me the script and send the SDK too. I can try to work it out.
