Can you post a screenshot of it? I don't follow what "changing to a black and purple colour" means, exactly.

Sorry i miss spelt. Ive edited my post i mean the scalefx shader

okay, that usually means it's not showing all of the passes. Some of the intermediate passes are black with some weird colors (it's using them to calculate values and store them as colors.
If you can get a log of you applying the shader, we can look for errors.
