Adding Canals to SH3 - How!

[Reece]

Getting more confused! Concerning the merging of Campaign_SCR.mis & NOK_SCR.mis file the latter contains:
[Unit 1944]
Name=GE Small Merchant#1
Class=KSS
Type=102
Origin=German
Side=0
Commander=0
CargoExt=1
CargoInt=0
CfgDate=19380101
DeleteOnLastWaypoint=false
DockedShip=false
GameEntryDate=19380101
GameEntryTime=0
GameExitDate=19451231
GameExitTime=0
EvolveFromEntryDate=false

and:
[Unit 1944.Waypoint 1]

Loop=-1
LoopProbability=100

My Campaign_SCR.mis contains:
[Unit 1944]
Name=Brest GE Coastal Merchant#33
Class=KSQ
Type=102
Origin=German
Side=2
Commander=0
CargoExt=2
CargoInt=0
CfgDate=19380101

DockedShip=false
GameEntryDate=19420101
GameEntryTime=0
GameExitDate=19440910
GameExitTime=0
EvolveFromEntryDate=true
Long=-547438.000000
Lat=5801577.000000
Height=0.000000
Heading=73.815300
Speed=7.000000
CrewRating=3
DelayMin=0
ReportPosMin=-1
ReportPosProbability=100
RandStartRadius=0.000000

and:
[Unit 1944.Waypoint 1]
Speed=7.000000

Loop=-1
LoopProbability=100
Long=-539538.000000

Also:
[Unit 2379]
Name=GE Small Merchant#1
Class=KSS
Type=102
Origin=German
Side=2
Commander=0
CargoExt=1
CargoInt=0
CfgDate=19380101
DeleteOnLastWaypoint=true
DockedShip=true
GameEntryDate=19410701
GameEntryTime=1200
GameExitDate=19441013
GameExitTime=1159
EvolveFromEntryDate=false
Long=2875746.000000
Lat=6843528.000000
Height=0.000000
Heading=60.000000
Speed=0.000000
CrewRating=3
DelayMin=0
ReportPosMin=-1
ReportPosProbability=100
RandStartRadius=0.000000
NextWP=0

This happens to other blocks as well such as:
[Unit 1943]
Name=GE Small Tanker#1

So I'm not sure what to edit or add to the scr layer here?
Should ther be 2 Blocks with the same "Name=" ?
or 2 Blocks with the same Name such as "[Unit 1943]" ?
Don't want to get it wrong as I've had too many CTD's!
