If table cell equals variable value

I've found plenty of help for deleting a row if a cell equals a number specified in the code, but I'm having trouble deleting a table row if the value of a cell equals the value of a variable. (This is my first ever attempt at VBA and first ever use of a site like this to seek help on any subject. I appreciate any help you can lend.)

Sub NeverGonnaWork

Dim x as String

x = Sheets("Sheet1").Range("B5").Value

Dim tbl as ListObject

Set tbl = Sheets("Sheet2").ListObjects("Table2")

'if column 15 in last row of the table equals x, delete that row of the table'

If Cells(tbl.ListRows.Count, (15)) = x then tbl.ListRows(tbl.ListRows.Count).Delete

End If

End Sub
