Hi Ashok,

Please try below code. I hope that will help you. 
public class ContactSearch
{
    public static List<contact> searchForContacts(string lastName, string MailingPostalCode)
	{
        List<contact> contactlist = [Select id, name from contact where lastname = :lastName and mailingpostalcode =:MailingPostalCode];
        return contactlist;
    }
}

In your code you was need adding the return type of method
public static List<contact> searchForContacts(string name,string MailingPostalCode)

Please let us know if this will help you

Thanks,

Hello,
I solved this challenge by writing the following code:::

public class ContactSearch {
    public static List<Contact> searchForContacts(String lastnm, String postno) {
        List<Contact> contacts = new List<Contact>();
        contacts = [SELECT ID, account.Name from Contact
                   where LastName = :lastnm AND MailingPostalCode = :postno];
        return contacts;
    }
}
But unfortunately, I got the following error:

Challenge Not yet complete... here's what's wrong: 
There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Insert failed. First exception on row 0; first error: FIELD_CUSTOM_VALIDATION_EXCEPTION, MailingPostalCode must be match account's ShippingPostalCode.: []

I don't understand how I should solve this error.
Could you help me, please???

Thanks in advance..

It look like you have validation rule on contact/Account object. Please deactivate the same and try again
Let us know if that will work
