Function has a local variable that's never read

Why: You created a local variable '{var}' inside this function, but no node ever reads it after assignment. It's just dead code. Fix: Either: (a) delete the variable and the Set node that writes to it, or (b) add a Get '{var}' node and connect it to wherever you actually need the value (if this was an oversight).
