vlookup函数好像有bug？

function test3(){

for (var i=1;i<12;i++){

var sheet1Cell=Application.Worksheets.Item("Sheet1").Cells.Item(1, i+2).Value2;

//var sheet2Cell=Application.Worksheets.Item("Sheet2").Cells.Item(j, 1).Value2;

//var sheet3Cell=Application.Worksheets.Item("Sheet3").Cells.Item(1, i).Value2;

var arr = Application.Worksheets.Item("Sheet2").Range("A1:B13");

Application.Worksheets.Item("Sheet3").Cells.Item(1, i+2).Value2= WorksheetFunction.VLookup(sheet1Cell,arr,2,true);

}

}

vlookup的数据如下。

结果如下
