outputfield bug??

小幫手好

以下選股程式碼回測都沒有問題，但是一旦把outputfield2的註解拿掉，選股回溯跟回測就都沒有任何交易，是啥原因呢?

input: minDY(3, "最低現金股利殖利率%") ; 

condition1 = getfield("現金股利殖利率", "D") > minDY ;
Outputfield1(getfield("現金股利殖利率", "D") , "現金股利殖利率") ; 

input: Y_period(3,"比較連續幾年股利"), minDividened(1, "股利都要大於N元");

condition2 = trueall(getfield("股利合計", "Y")>minDividened, Y_period) ;
//Outputfield2(getfield("股利合計","D"), "股利合計") ; 

condition99 = condition1 and condition2 ; 

if condition99 then ret=1;
