Hide Row Based on Error in Cell--Excel 2010

[LadyNatira]

I would like to hide entire rows if there is a #NUM! error in a specific column--column U in this case. I've tried this:

Sub Macro1()
Columns("U").SpecialCells(xlCellTypeFormulas, 16).EntireRow.Hidden
End Sub

. . . for which I get a Hidden method of Range class failed error.

Any suggestions?
