Deleting Rows From a dataset

I am trying to delete a range of rows from a dataset. The rows that I am trying to delete conatin account numbers with the first three characters = 231. My account numbers are in column b and l is defined as a row on the worksheet.

The code I am trying to use is as follows:

If Left(Range("b" & l), 3) = 231 Then Rows("l").Delete

I do not know why it will not work and I am not getting an error message. Any suggestions?
