Could you please upload the screenshot directly (or copypaste the error as plaintext) instead of using a URL shortener? I have no way of knowing if that link is a valid image or a site that will steal all my credentials.
Change the first line of both the affected scripts like this and it should work:
var a = argument1, b= argument0;
Basically the problem is that the collision scripts need to take two arguments (x and y) but some shapes don't have collisions based on the x/y values, so they don't use the arguments. We can work around this using dummy variables. When the engine was originally made, it didn't matter that every argument was used, just the last... and then in the latest version(s) this was changed to require using every argument.
