Move a file from one File Upload Field to another

Move a file from one File Upload Field to another

Hey All,

Can anyone help me solve a problem i'm having where I move a document from one File Upload Field, and another.

I figured it would be as simple as trying to change the File_ID on the 2nd File Field with the data from the 1st File Field, but it does not seem to work. I am guessing I need to download the file from 1, and attach it to 2.

Heres the code i'm working with:
  1. Cert = zoho.crm.getRecordById("House_Certification",CertID);
    //
    CIssued = Cert.get("Issued");
    CExpiry = Cert.get("Expiry");
    NIssued = Cert.get("New_Issued");
    NExpiry = Cert.get("New_Expiry");
    NAttached = Cert.get("New_Certificate_Attached");
    //
    NCertFile = Cert.get("File_Upload_3").toMap();
    NCertFileID = NCertFile.get("file_Id");
    //
    updateCert = Map();
    // Fill Main Info
    updateCert.put("Issued",NIssued);
    updateCert.put("Expiry",NExpiry);
    updateCert.put("Served_to_Tenants",'Action Required');
    updateCert.put("House_QR",'Action Required');
    updateCert.put("Current_Certificate",NCertFileID);
    // Clear Add New Cert
    updateCert.put("New_Issued",null);
    updateCert.put("New_Expiry",null);
    updateCert.put("File_Upload_3",null);
    updateCert.put("Confirm_Add_New_Cert",null);
    updateCert.put("Add_New_Certificate",null);
    //
    update = zoho.crm.updateRecord("House_Certification",CertID,updateCert);
    info update;
