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;

Learn how use the CAT functions in SAS to join values from multiple variables into a single value.
