Criteria Is Passed By Function Call

Dear Access Query Expert

I have created a query which has a function call as the criteria for one of the numerical fields. The function returns a string expression such as .....

1) 132 OR 142 OR 156
2) 132 OR 142
3) 132

..... into the criteria section of the numerical field.

Unfortunately, the query doesn't work if the criteria is generated by the function call. However, if I hardcode the criteria (don't send a function call but directly write 132 OR 142 OR 156) the query works.

I am puzzled and I am not sure how to solve this problem.

Thank you so much.
