XS編譯問題

請問我如何自動選股出周K&日K二者時區符合5均線大於10均線篩選

var:value1D(0),value2D(0),value1W(0),value2W(0);

value1D = average(GETFIELD("close", "D"), 5);

value2D = average(GETFIELD("close", "D"), 10);

value1W = average(GETFIELD("close", "W"), 5);

value2W = average(GETFIELD("close", "W"), 10);

condition1 = value1D > value2D;

condition2 = value1W > value2W;

if condition1 and condition2 then ret =1;

系統錯誤顯示:無法使用RET指令

有高手能幫忙重新撰寫或告知問題在哪嘛?

謝謝
