Hi I try to create a Custome Study via chat GPT and get this error message. Can someone tell me what I'm doing wrong?
Code :

#include "sierrachart.h"

SCDLLName("SMT Divergenz Linie")

SCSFExport void scsf_SMT_Divergenz_Linie(SCStudyInterfaceRef sc)
{
SCInputRef ChartNumA = sc.Input[0];
SCInputRef ChartNumB = sc.Input[1];
SCInputRef Lookback = sc.Input[2];
SCInputRef LineColor = sc.Input[3];

if (sc.SetDefaults)
{
sc.GraphName = "SMT Divergenz Linie";
sc.StudyDescription = "Zeichnet SMT Divergenzen zwischen zwei Charts ein";
sc.AutoLoop = 1;

ChartNumA.Name = "Chart Nummer A";
ChartNumA.SetInt(2);

ChartNumB.Name = "Chart Nummer B";
ChartNumB.SetInt(3);

Lookback.Name = "Lookback-Bars für Pivot";
Lookback.SetInt(3);
Lookback.SetIntLimits(1, 20);

LineColor.Name = "Linienfarbe";
LineColor.SetColor(RGB(255, 0, 0));

return;
}

int chartA = ChartNumA.GetInt();
int chartB = ChartNumB.GetInt();
int lb = Lookback.GetInt();
COLORREF color = LineColor.GetColor();

// Sicherheitsprüfung
if (sc.Index < lb || sc.Index + lb >= sc.ArraySize)
return;

SCFloatArray highA, lowA, highB, lowB;

sc.GetChartBaseData(chartA, SC_HIGH, highA);
sc.GetChartBaseData(chartA, SC_LOW, lowA);
sc.GetChartBaseData(chartB, SC_HIGH, highB);
sc.GetChartBaseData(chartB, SC_LOW, lowB);

if (highA.GetArraySize() == 0 || highB.GetArraySize() == 0)
return;

// Swing High
bool isHighA = sc.High[sc.Index] > sc.High[sc.Index - lb] && sc.High[sc.Index] > sc.High[sc.Index + lb];
bool isHighB = highB[sc.Index] > highB[sc.Index - lb] && highB[sc.Index] > highB[sc.Index + lb];

if (isHighA && isHighB)
{
float diffA = sc.High[sc.Index] - sc.High[sc.Index - lb];
float diffB = highB[sc.Index] - highB[sc.Index - lb];

if ((diffA > 0 && diffB < 0) || (diffA < 0 && diffB > 0))
{
s_UseTool tool;
tool.Clear();
tool.ChartNumber = sc.ChartNumber;
tool.DrawingType = DRAWING_LINE;
tool.BeginIndex = sc.Index - lb;
tool.EndIndex = sc.Index;
tool.BeginValue = sc.High[sc.Index - lb];
tool.EndValue = sc.High[sc.Index];
tool.Color = color;
tool.LineWidth = 2;
tool.Text = "SMT High Divergenz";
tool.AddMethod = UTAM_ADD_ALWAYS;
sc.UseTool(tool);
}
}

// Swing Low
bool isLowA = sc.Low[sc.Index] < sc.Low[sc.Index - lb] && sc.Low[sc.Index] < sc.Low[sc.Index + lb];
bool isLowB = lowB[sc.Index] < lowB[sc.Index - lb] && lowB[sc.Index] < lowB[sc.Index + lb];

if (isLowA && isLowB)
{
float diffA = sc.Low[sc.Index] - sc.Low[sc.Index - lb];
float diffB = lowB[sc.Index] - lowB[sc.Index - lb];

if ((diffA < 0 && diffB > 0) || (diffA > 0 && diffB < 0))
{
s_UseTool tool;
tool.Clear();
tool.ChartNumber = sc.ChartNumber;
tool.DrawingType = DRAWING_LINE;
tool.BeginIndex = sc.Index - lb;
tool.EndIndex = sc.Index;
tool.BeginValue = sc.Low[sc.Index - lb];
tool.EndValue = sc.Low[sc.Index];
tool.Color = color;
tool.LineWidth = 2;
tool.Text = "SMT Low Divergenz";
tool.AddMethod = UTAM_ADD_ALWAYS;
sc.UseTool(tool);
}
}
}



i get this error, sorry it is in german:
