Trigger for copy Lead text field values into same lead lookup field

Hi Everyone,

I don't have much knowledge about coding. I have tried few triggers using some developers sample available in discussion board. But i can't able to acheive my goal. My requirement is given below.

There are a few fields that cannot be updated through the standard SalesForce interface, and can only be updated via Apex code.  We need to duplicate some information from a text field on the Lead and Opportunity screens, and populate it into a lookup field.  Please see the details below:

Object - Lead
Originating field (from) - Referral Text (text)
Destination field (to)  - Referral Partner (lookup)
When to trigger - Upon update/Insert of Referral Text value

Can anyone please help on this.

Thanks in advance.

My trigger which i have created is given below. But it doesn't work.

       trigger Referral_Lead on Lead(After insert || After Update) { {
        for(Lead newLead:Trigger.new){       
            if (newLead.Referral_Text__c!=null) {            
                String refString = newLead.Referral_Text__c;           
                Id referralID = refString;           
                newLead.Referral_Partner__c = referralID;      
            }     
        }   
    }
    }

1. Lookup field is refrence field and cannot hold arbitory text. It has to Id.
2. While assigning String to Id, you have to type cast it. If String is a valid id, it will typecast properly, else will throw error. and you have to handle execption accordingly.
