I have a error

link text

I have a error that i do not understand, below is a pdf file of the error and some pictures. Thank you!

“Accessed None” means node is accessing not set object link/varable, a null object, a none object and “Target” pin can not accept “None” because it would call function on nothingness (which in C++ would cause heavy crash). In you case it selams “Point 1” and Point 2" is not set, there are None they are nothing and you can’t call “AI MoveTo” on them, if not make sure you not feeding any “None” in to AI MoveTo node
