VBscript Zeilen verbinden und rechnen

Hallo liebe Mitglieder,

Ich habe ein kleines Problem.

Ich würde gerne die Zeilen mit den Namen "Werte" mit den Zeilen mit darunter verbinden.
Und dann bei werte an dritter Stelle nach Komma Trennung den wert von Offset/werte abziehen. -> -3.66976-0.30079=-3.97055

Hoffe ihr könnt mir helfen.
Vielen Dank

Original:

Daten,2,12,2322
Daten,1,11,2
Daten,13,6,2
Werte,12.56778,0.45333,-3.66976
Werte,-12.56778,0.45333,-3.66976
Werte,11.56778,0.35333,-3.66976
Werte,13.56778,0.55333,-3.66976
Werte,9.56778,0.77333,-3.66976
Werte,7.56778,0.45285,-3.66976
,0.33334,0.30000,-0.96666
,0.23334,0.40000,-0.96666
,0.13334,0.20000,-0.96666
,0.03334,-0.10000,-0.96666
,0.43334,0.00000,-0.96666
,0.93334,0.00000,-0.96666
offset/werte,0,0.30079

Geändert sollte so aussehen:

Daten,2,12,2322
Daten,1,11,2
Daten,13,6,2
Werte,12.56778,0.45333,-3.97055,0.33334,0.30000,-0.96666

Werte,9.56778,0.77333,-3.97055,0.43334,0.00000,-0.96666
Werte,7.56778,0.45285,-3.97055,0.93334,0.00000,-0.96666
