text created by object code does not appear on my bar chart?

 

All of a sudden the text created by the object code shown below does not appear on my bar chart.

The objects list properly displays the name as "Objname4" but the description column now displays the word "Label" instead of the msg4 text?

The program compiles without error. What must I do to correct the problem?

ObjectCreate("ObjName4", OBJ_LABEL, 0, 0, 0);
msg4= "ratio: spread[$]//band[$]="+DoubleToStr(spread*conv_fac/(sell_buy_diff*conv_fac)*100, 0)+"%"
+" ratio: band//avg lng="+DoubleToStr(( sell_buy_diff/(avg_bar_length) )*100,0)+"%";
ObjectSetText("ObjName4",msg4,12,"Arial Black", Black);
ObjectSet("ObjName4", OBJPROP_CORNER, 0);
ObjectSet("ObjName4", OBJPROP_XDISTANCE, 0);
ObjectSet("ObjName4", OBJPROP_YDISTANCE, ydist_base_displace + v4);
