I am a novice at Excel VBA and am running into an error 1004 while compiling a portion of the code:

```
Cells(i, j).Formula = _"=vlookup(Cells(i,1).Value,SKULifeCycle_Table_Temp!R1C1:R5000C500,match(Cells(1,j).Value,'SKULifeCycle_Table_Temp'!R1C1:R1C500,0),0)"

```

`i` and `j` have been defined previously as integers and are part of a for loop. Could anyone please help me out on this?
