I want a note that is added to a drawing by macro to automatically add the part weight.

The following is an extract of the code

cmb_note_list.AddItem "Moulding"
note(1) = "Notes:" + Chr(13) + Chr(10) + _
"1. All necessary draft to be 1.0º max." + Chr(13) + Chr(10) + _
"2. All unspecified radii to be R1 max." + Chr(13) + Chr(10) + _
"3. Exterior surfaces (except where indicated)," + Chr(13) + Chr(10) + _
"   to have a spark finish equivalent to VDI 36 or Ra 6.3." + Chr(13) + Chr(10) + _
"   All other surfaces to be N6 max." + Chr(13) + Chr(10) + _
"4. To be moulded in accordance with material" + Chr(13) + Chr(10) + _
"   manufacturers instructions" + Chr(13) + Chr(10) + _
"5. Component Weight = ???gms" + Chr(13) + Chr(10) + _
"6. 3D IGES file available." + Chr(13) + Chr(10) + _
"7. Number of impressions = ?" + Chr(13) + Chr(10) + _
"8. Tool to be marked 'Property of XXXXX AT No.?????'" + Chr(13) + Chr(10) + _
"9. This is a mating part with ???"

I wish to replace ??? with the weight of the part, how do I achieve this?
