Set trigger to select multiple values in a field from a variable
I have created an input box where a user can paste multiple values of a field. So a user will post mutiple values for a field in the input box and I am storing that in a varibale. I am not sure how can I set up a trigger that would take the values from the variable and select a field with those multiple values.
I know how to set up a trigger if there is only one value but for mutiple values its not working.
