Button Question

The cell, pasted below, is in my notebook. When the cell is evaluated,
It prints a button, labeled simulate, but clicking on the button does
not  print the six simulated integers that RandomInteger  computed.

The error message says that the list of probabilities, entered as
shown below, is not a probability distribution recognized by the
system, but {1/6,1/6,1/6,1/6,1/6,1/6} is a valid multinomial
distribution.

ButtonEvaluator, not mispelled, is printed in red. The color red must
be an indication of an error of some kind, but I have no idea what it
is.

Cell[ButtonBox["Simulate", Active -> True,
   ButtonFunction ->
    Print[RandomInteger[
      MultinomialDistribution[
       100, {"1", "/", "6", "1", "/", "6", "1", "/", "6", "1", "/",
        "6", "1", "/", "6", "1", "/", "6"}], 1]],
   ButtonEvaluator -> Automatic] // DisplayForm, "Output"],

In one example, I saw, the arrow between ButtonFunction and Print is
short and preceded by a colon. If if that notation is necessary, I
don't know how to do it.

Helpful advice will be appreciated .

John
