MAcro help

[Sofia Grave]

I have a question, I am making a goal seek using
the followed the code. And is working, but I want to add
something else. The numbers for this macro depend on
values in another sheet and when I don't have any data in that range
I receive a debug error. And what I want is, if in the
range [b23:m33] (data in another sheet) some cells are null (empty cell),
the macro jumps
to next (number2). Because when the debug appears
only runs the goal seek for number1. I want to avoid to
open all the time the debug and comment the extra lines
that the debug shows.

number 1 and number 2 depends on the data from range [b23:m23]


Private Sub Worksheet_Change(ByVal Target As Range)

If Intersect(Target, forside.Range("B6:B7")) Is Nothing Then
Exit Sub
Else
'number1
.Range("D45").GoalSeek goal:=0, changingcell:=.Range("D44")
.Range("f45").GoalSeek goal:=0, changingcell:=.Range("F44")
.Range("h45").GoalSeek goal:=0, changingcell:=.Range("H44")
.Range("J45").GoalSeek goal:=0, changingcell:=.Range("J44")

'number2

.Range("D45").GoalSeek goal:=0, changingcell:=.Range("D44")
.Range("f45").GoalSeek goal:=0, changingcell:=.Range("F44")
.Range("H45").GoalSeek goal:=0, changingcell:=.Range("H44")
.Range("J45").GoalSeek goal:=0, changingcell:=.Range("J44")

End If

End Sub

Could someone help me

Thanks
