This error message seems a little off.  It looks like the entire chi squared
test was divided by 6.  Notice that the /6 occurs *after* the closing
parenthesis for the test.

As others have noted, it is probably an input problem, but here is another
sample of code you could try.

## all of the data is entered directly into the function.  x is the data, p
are the probabilities.
## the biggest difference is rather than dividing by 6 to make the
probabilities sum to 1, the argument "rescale.p=T" will make sure that they
sum to 1

chisq.test(x=c(22,21,22,27,22,36), p=c(1,1,1,1,1,1), rescale.p=T)

        Chi-squared test for given probabilities
data:  c(22, 21, 22, 27, 22, 36)
X-squared = 6.72, df = 5, p-value = 0.2423

Best of luck to you!  I have found the list to be very helpful and
informative.
