请高手给修复一个通达信的技术指标，先谢谢了！

Question

这个指标在安装时会出现如下提示：
错误句 :
DRAWTEXT(ISLASTBARANDC,4,17),COLOR0000BB
详细信息 : 未知字符串 ISLASTBARANDC
错误起始位置 : 334 ; 长度: 13
以下附上源码，请高手赐教：
A1:=AMOUNT/VOL/100;
A2:=(3*HIGH+LOW+OPEN+2*CLOSE)/7;
A3:=SUM(AMOUNT,40)/A1/100;
A4:=SUM(AMOUNT,80)/A1/100;
B1:=DMA(A2,VOL/A3);
B2:=DMA(A2,VOL/A4);
B3:=(CLOSE-B1)/B1*100;
B4:=(CLOSE-B2)/B2*100;
