[Sims 4] Problem Creating Custom Objects

[weirddude94]

So I'm trying to make a some custom pictures (basically just modifying the textures using sims4studio) that promote a heavy flirty emotion buff. I attempted to follow a tutorial, but I flubbed something up apparently because no matter what I do, when I try to place the object, it just says something like "Script Error" and doesn't place it. Can anyone provide some help with getting started with this?
