你好，我的全局变量这样写的：
int ii, jj, kk1, kk2;
jj=GetTagByte("ack_flag");
ii=GetTagByte("my_valve");
if(jj==1);
{
if(ii==1) SetTagChar("ack_text", "YOU ARE GOING TO OPEN THE VALVE NO WB1");
else if(ii==2) SetTagChar("ack_text", "YOU ARE GOING TO OPEN THE VALVE NO WB2");
else if(ii==3) SetTagChar("ack_text", "YOU ARE GOING TO OPEN THE VALVE NO WB3");
else SetTagChar("ack_text", "ERROR ERROR ERROR！！！");
}
可加不上大括号啊
能说的详细一点吗，谢谢
