Outpufield問題

我想要寫一個觀察每日主投動向的腳本如下，條件是每日主投買超過1000張或1億就選進來

value1=GetField("主力買賣超張數","D");

value2=GetField("開盤價","D");

value3=GetField("投信買賣超","D");

value4=GetField("開盤價","D");

value5=IFF(value1*value2*1000>100000000 or value1>1000,1,0);

value6=IFF(value3*value4*1000>100000000 or value3>1000,1,0);

if value5+value6=2 

then ret=1;

outputfield(1, getfield("主力買賣超張數","D"),2,"主力買超");

outputfield(2, value1*value2/100000,2,"主力買超$$(億)");

outputfield(3, getfield("投信買賣超","D"),2,"投信買超");

outputfield(4, value3*value4/100000,2,"投信買超$$(億)");

到此為止執行以及選股完全沒有問題

但我想要再加一個outputfield欄位，一起把上周的400張大戶持股增減也加進來一起看

因此最後面再多加了一行

outputfield(5,getfield("大戶持股比例","W",param:=400)-getfield("大戶持股比例","W",param:=400)[1],1,"增加比例");

卻會造成選股抓不到東西，是哪裡有錯嗎QQ
