Conditional formatting for percentage formatted cells

I have posted before about conditional formatting and I have a piece of code that works for integer numbers but when I try to implement it for a cell that is formatted to percentages it doesn't work. The cells are also formatted with a formula. Sample workbook and code attached, I would greatly appreciated anyone who could help me.

Formula:

Sub ConditionalFormatting()



lLow = -3



lHigh = 50



Set rng = Range("H5:H19, H21:H24, H26:H29, H26:H29, H31:H36, H38:H44") 'Range

rng.FormatConditions.Delete  ' delete any pre-existing formatting



' add greater than condition

With rng.FormatConditions.Add(xlCellValue, xlGreater, lHigh)

   .Interior.Color = rgbRed

End With



' add less than condition

With rng.FormatConditions.Add(xlCellValue, xlLess, lLow)

   .Interior.Color = rgbGreen

End With



' add middle condition

With rng.FormatConditions.Add(xlCellValue, xlBetween, lHigh, lLow)

   .Interior.Color = rgbGold

End With



End Sub
