Excel VBA中的VLOOKUP公式不起作用

Question

I am trying to make this formula work in VBA, but it keeps telling that "B2" is supposed to be the end of the statement. The code is provided below:

With Range("J2:J" & LastRow)
    .Formula = "=I2/VLOOKUP(A2&"B2", MARM!A:G, 7, 0)"
    .Value = .Value
End With

If I want for the formula, when it is 0 or #N/A to leave the cell empty I used the code but it is not working.. Any ideas?

.Formula = "=IF(VLOOKUP(A2&""B2"",MARM!A:G,7,0)=0,"""",VLOOKUP(A2&""B2"",MARM!A:G,7,0))"

Answer 1

Edit

With Range("J2:J" & LastRow)
.Formula = "=IF(IFERROR(I2/VLOOKUP(A2&""B2"",MARM!A:G,7,0),"""")=0,"""",IFERROR(I2/VLOOKUP(A2&""B2"",MARM!A:G,7,0),""""))"
.Value = .Value
End With
