Missing operator or semicolon 错误帮忙找一下，谢谢了
adoquery3.close;
adoquery3.sql.clear;
adoquery3.sql.Add('SELECT count(*) FROM RFIDreadwrite,rfidrw,ProductionTaskAllocation WHERE RFIDreadwrite.rfid_add = RFIDRW.rfidrw_add AND rfidrw.rfidrw_id = ProductionTaskAllocation.rfidrw_id and ProductionTaskAllocation.kb_id='''+combobox7.Text+'''');

adoquery3.open;
with adoquery3 do

Edit4.Text:=inttostr(Fields(0).Value); //查询生产品的数量

这段代码哪里有错误的，应该怎么改？运行的时候会出现错误Missing operator or semicolon

谢谢了

[解决办法]
Fields(0).Value改为Fields[0].Value
