ChartXYToTimePrice is only working for one OBJ_CHART out of the 4 i have

[Chye Thiam Tan]

hi guys,

i need to ask for some guidance on ChartXYToTimePrice. my code with ChartXYToTimePrice seems to only work with the first OBJ_CHART. i have created 4 OBJ_CHARTs (tiled) and would like to use ChartXYToTimePrice on each of them to get the Time and Price of current clicked chart. its able to determine the chart that i clicked correctly, but ChartXYToTimePrice is giving me ERR_CHART_WRONG_PARAMETER (4107) for the 2nd, 3rd and 4th one. Below is my code and my results..  Appreciate if anyone can help. 

int subwindow = 0;
datetime datetimeclick = TimeCurrent();; 
double priceclick = 0;
bool clicksuccess = false;
long clickchartid;

 case CHARTEVENT_OBJECT_CLICK:             
         Print("CHARTEVENT_OBJECT_CLICK: ", sparam); 
         clickchartid = ObjectGetInteger(0,sparam,OBJPROP_CHART_ID); 
         Print("Before ChartXYToTimePrice: ", clickchartid," ", CWnd::MouseX()," ", CWnd::MouseY()," ", subwindow," ", datetimeclick, " ", priceclick);  
         ResetLastError();       
         clicksuccess = ChartXYToTimePrice(clickchartid,CWnd::MouseX(),CWnd::MouseY(),subwindow,datetimeclick, priceclick);         
         if(!clicksuccess) Print(GetLastError());
         Print("After ChartXYToTimePrice: ", clicksuccess, " " ,clickchartid, " ", CWnd::MouseX(), " ", CWnd::MouseY(), " " , subwindow, " ", datetimeclick, " ", priceclick);
         ChartRedraw();                       
         return;
