creating a formula field has NO impact on record selection (unless it is enforcing a join that was not already enforced).
As I stated earlier you have to write a select statement (a boolean formula) inside the select expert to do this.
putting
table.field = {?parameter}
into the select expert will limit the rows to whenever this evaluates to TRUE
this will only evalaute to true when the table.field (your database field) has as string (text) value = to any string value (1,2,3,4 or 8) entered into your parameter at run time.
