MT4: Create objects in Tester in new build MT4

Hi guys,
I canno´t object in tester mode MT4.
My code:
void Error()
{ string name="Error";
if(!ObjectCreate(current_chart_id,name,OBJ_TEXT,0,0,0))
{
Print("Error: can't create object name:", name," code #",GetLastError());
return;
}
ObjectSetDouble(current_chart_id,name,OBJPROP_PRICE,Low[0]-100*Point);
ObjectSetInteger(current_chart_id,name,OBJPROP_TIME,Time[0]);
ObjectSetInteger(current_chart_id,name,OBJPROP_COLOR,clrWhite);
ObjectSetString(current_chart_id,name,OBJPROP_FONT, "Wingdings" );
ObjectSetString(current_chart_id,name,OBJPROP_TEXT, CharToStr(141) );
}

in tester function end with error GetLastError() 4202.

The same code input to script works all right.

I don´t know when I have error.
Can you help me? Thank you.
