The following code is for a generic FindAll code. This can also be used by setting the Application.FindFormat so it can be used with conditional formatting.

End With
Set FoundRange = FindAll("", LookIn:=xlFormulas, SearchWhat:=Range("K6:M200"), SearchFormat:=True)

Optional SearchWhat As Variant, _
Optional LookIn, _
Optional LookAt, _

Optional SearchDirection As XlSearchDirection = xlNext, _
Optional MatchCase As Boolean = False, _
Optional MatchByte, _
Optional SearchFormat) As Range
'LookIn can be xlValues or xlFormulas, _
LookAt can be xlWhole or xlPart, _
SearchOrder can be xlByRows or xlByColumns, _
SearchDirection can be xlNext, xlPrevious, _
MatchCase, MatchByte, and SearchFormat can be True or False. _
Before using SearchFormat = True, specify the appropriate settings for the Application.FindFormat _
object; e.g. Application.FindFormat.NumberFormat = "General;-General;""-"""
