Try removing the square brackets that encapsulate your weight, they
are present in the syntax diagram for the -table- command to indicate
that the use of weights is optional, they are not  required when
actually invoking -table- with weights.

You also have a semi-colon at the end of the line which is probably unnecessary.

Your use of the -, format()- option doesn't look right to either as
you appear to be using it twice, once without specifying any actual
format and a second time you use the abbreviated form, but don't use
the correct format.

Finally you can combine the -sort- and -by- into one by using -bysort-, so try

bysort cmanew: table vismin lf_act weight = wt, c(sum counter)
format(%9.0) col row center
