求高手指点有关用*get命令提取节点温度时的错误

命令流为：
*DO,i,1,emax
TTEMP=0
*DO,j,1,8
*GET,TEMP,NODE,NELEM(i,j),NTEMP
TTEMP=TTEMP+TEMP
*ENDDO
TTEMP=TTEMP/8
*GET,P,ELEM,I,ATTR,LIVE
*IF,TTEMP,GE,1500,AND,P,EQ,1,THEN
EKILL,i
*else
*if,ttemp,lt,1500,and,p,eq,-1,then
ealive,i
*endif
*endif
*enddo
提示是：
*** WARNING *** CP = 5.969 TIME= 15:25:01
The data for *GET entity NODE item NTEMP and NODE= 3073 is not defined.

The *GET command is ignored.

跪求高人指点~~
