What is wrong with the code you show us?

You may want to describe what you are attempting and what you mean by "specfic variable"

 

I know that you likely don't like that your Log shows something like:

NOTE: No statistics are computed for Gender * Prices100 because Prices100 has less than 2 nonmissing levels.

You have restricted one of the variables to only allow one level, "RM101-RM400", and when you have a two-way chi-square the calculations just do not work that way as you are introducing a divide-by-zero condition.

 

You can run a chi-square on a single variable such as:

Proc freq data=sashelp.class;
   tables age /chisq;
run;

And the results reflect the levels of the single variable.

I suspect that you may have wanted if the question you wanted answered was "is the distribution of Gender the same/different when Prices100 has this specific value".

proc freq data=AddnewPrice;
   TABLES Gender
       /chisq;
    where Prices100 = "RM201-RM400";
run;
