I'm looking to create a function in Excel/VBA that will look at a range of cells and return a value of TRUE if any of the cells contains a certain character (an asterisk *). There will be some blank cells, some cells will contain text and some may contain text and an asterisk. Can anyone help? Many thanks

Hello,

You may use the following formula on a worksheet:

=NOT(ISERROR(MATCH("*";$A$1:$A$10;0)))

But, "~" must be specified as "~~". For example:

=NOT(ISERROR(MATCH("~~";$A$1:$A$10;0)))

VBA functions:

VB

Function MyMatch(ByVal lookup_value As Variant, ByVal lookup_range As Variant) As Long

On Error Resume Next

Dim index As Long

index = InStr(1, lookup_value, "~", vbBinaryCompare)

If index > 0 Then
    lookup_value = Replace(lookup_value, "~", "~~")
End If

MyMatch = Application.Match(lookup_value, lookup_range, 0)

End Function

Function HasValue(ByVal lookup_value As Variant, ByVal lookup_range As Variant) As Boolean

HasValue = (MyMatch(lookup_value, lookup_range) > 0)

End Function
