Due to the way minification works, you can't expect to call a name like that.
What you have to do is use picking, to get the object into the selected objects list.
You can use uid, as well as iid, however those are prone to change at runtime. I would suggest the simplest method... using a variable.
Like: If global variable makeObject = 1, system make sprite at x,y.
Its a little long and draw out, but its hard to screw up.
