> g[X_String,w_Real,f_]:=Text[Style[X,12,Bold],{w,f/.{x->w}},{0,-2}]; Among other things, you'll need to replace _Real with _?NumberQ. 3 does not have a head of Real. Also, because Plot has Attributes[Plot] = {HoldAll,...}, you'll need to wrap Epilog->{g...} in Evaluate to make sure g gets replaced by the correct value. At this point, if you put //Trace after each version of the Plot command, you can see that both end up evaluating the same thing. And both do produce the correct plot. Hope this helps. -Richard
