If A and B are the same, print all the C in D with commas between them

Above is an example and I was wondering if I should use Vlookup but I could only do it with one column??

Is there a formula for such as this?

Thank you in advance.

Having the results in a single cell in D requires that you add
the following function code in VBA to your workbook as a module...

Function aconcat(a As Variant, Optional sep As String = "") As String
' Harlan Grove, Mar 2002
Dim y As Variant
If TypeOf a Is Range Then
For Each y In a.Cells
aconcat = aconcat & y.Value & sep
Next y
ElseIf IsArray(a) Then
For Each y In a
aconcat = aconcat & y & sep
Next y
Else
aconcat = aconcat & a & sep
End If
aconcat = Left(aconcat, Len(aconcat) - Len(sep))
End Function

Now equipped with ACONCAT...

D2, control+shift+enter, not just enter, and copy down:

=SUBSTITUTE(aconcat(IF($A$2:$A$8&"|"&$B$2:$B$8=A2&"|"&B2,","&$C$2:$C$8,"")),",","",1)

Thank you but it doesn't work.
I've copied and pasted the function by going into
Developer -> Visual Basic -> ThisWorkBook -> *paste*

and saved it.
and then used the formula you've given me.

I use XL2007.

Thank you.

In order to add the function to your wb, run...

ALt+F11
Insert|Module
File|Close and Return to Microsoft Excel.
