I need some help with code so that the study value tracks the last price on the main graph. Just like you can do with the countdown timer study. Here's the code.

Thanks
JDConner

SCSFExport scsf_LargeTextDisplayForStudyFromChart(SCStudyInterfaceRef sc)
{
  SCSubgraphRef TextDisplay = sc.Subgraph[0];

  SCInputRef HorizontalPosition = sc.Input[0];

  SCInputRef SubgraphOffset = sc.Input[5];

  
  if (sc.SetDefaults)
  {
    // Set the configuration and defaults
    
    sc.GraphName = "Text Display For Study from Chart";

    TextDisplay.Name = "Text Display";
    TextDisplay.LineWidth = 20;

    // During development set this flag to 1, so the DLL can be modified. When development is completed, set it to 0 to improve performance.
    sc.FreeDLL = false;

    return;
  }
  
  // Do data processing

  if (sc.HideStudy)//do nothing if study is hidden
    return;

  s_UseTool Tool;

  Tool.Clear(); // Reset tool structure for our next use. Unnecessary in this case, but good practice.
  Tool.ChartNumber = sc.ChartNumber;
  Tool.DrawingType = DRAWING_TEXT;
  
  Tool.LineNumber = 79212343+ (sc.StudyGraphInstanceID);
  if(!DisplayInFillSpace.GetYesNo() && !sc.Input[8].GetYesNo())
