Can you please help me out?

Hi All,

I have Location and student objects are there. In Location object multiselect picklist paymentmode is there with values(ACH,Check,Cash) and student is lookup to location and even in Student i have picklist called paymentmode with values(ACH,Check,Cash).
 Requirement is Whatever the values i selected in Location only those values should appear in student. I tried following code but it is not working
<apex:inputField value="{!Student__c.Payment_Mode__c}">
                  <apex:actionSupport event="onchange" action="{!picklistFunction}"/>

    public PageReference picklistFunction()
        List<Student__c> studentList = new List<Student__c>();
        List<Student__c> stuList = [select id,name,Payment_mode__c,Location__c,Location__r.Payment_mode__c from Student__c];
        for(Student__c st : stuList)
            st.payment_mode__c = st.Location__r.Payment_Mode__c;
           update studentList;
        return null;

Hi jagadeesh,

In student obj u can create one formula field in that store "Location__r.Payment_mode__c" its a simple solution.

Mark its as best answer if its helps.

Hi Praveen,

It is giving error saying that  Error: Field Payment_mode__c is a multi-select picklist field. Multi-select picklist fields are only supported in certain functions.
