Data in form "A" not saving in form "B" in a nested IF/ ELSE statement

Data in form "A" not saving in form "B" in a nested IF/ ELSE statement

I have a customer service app (Form "A") that needs to save a date back to (customer_Info)  form "B". The code is nested in a IF/ ELSE statement. The rest of the function works, but the updated date is not saving back to form "B". It is populated by the ID of form "B". ---> SiteInfo  =  Customer_Info  [ID == input.Site_ID];

This section sends the email ok and with all of the info from form "B". It dose not save the date into form "B". What am I missing?

// If the service is marked completed and the Request_Type is CCTV Service send this email.
else if ((input.Service_Status  ==  "Completed")  &&  (input.Request_Type  ==  "CCTV Service"))
{
    // Store the date of this CCTV service in the Customer form.
    SiteInfo.CCTV_Service_Date = zoho.currentdate;
    info SiteInfo.CCTV_Service_Date.getall();
    //
    sendmail
