Update another table from button

Hi,
I have a button on grid of list page.
This is my button instructions: -

• Client before
  
  ctrl.setMessage("Sending request to server...");
  
• Server (and this is where I'm battling)
  
  IF ($values["V1"]==0) { //instruction or condition to update table then follow through
  
  global $dal;
  
  $record = $button->getCurrentRecord(); //this is the button being clicked on list grid & I'm sure it's confusing the entire process
  
  if ($record["ID"])
  
  {
  
  $Stock = $dal->Table('Stock');
  
  $Stock->Param['ID'] = $record['SID1'];
  
  $Stock->Value['Stock_on_Hand'] = ($record['CSOH1'] + $record['T1']);
  
  $Stock->Update();
  
  }
  
  }
  
  else
  
  {
  
  // do nothing
  
  }
  
  $result["txt"] = $params["txt"]."Updated !!!!! ";
  
  • Client After
    
    var message = result["txt"];
    
    ctrl.setMessage(message);
    The problem I'm experiencing is when clicking the button it still updates the table irrespective of the condition.
    Thanks
