Custom Value Save/Load

[Killerphill]

I am trying to make a simple save/load trigger that only remembers the custom value of a unit. I have looked through all the tutorials i can find, but none of these have custom values. The load works when i load the code on the same map, but when i restart, it loads with the custom value reset to 0. I have it that the custom value is converted to a string, saved in a variable, then later converted back to a custom value and given to a unit. I dont know why this trigger isn't working, and would like if someone could help me out.

• Initialization
  • Events
    • Map initialization
  • Conditions
  • Actions
    • Set CusValCode = ((Name of Player 1 (Red)) + (((String((Count structures controlled by Player 1 (Red) (Exclude incomplete structures)))) + (String((Count non-structure units controlled by Player 1 (Red) (Exclude incomplete units))))) + ((String((Player 1 (Red) Current gold)))
    • Trigger - Turn off (This trigger)

• Save
  • Events
    • Player - Player 1 (Red) types a chat message containing -save as An exact match
  • Conditions
  • Actions
    • Set FinalCode = Empty String
    • Set CusVal = (Custom value of Paladin 0005 <gen>)
    • Set FinalCode = CusValCode
    • Set CusValString = (String((Custom value of Paladin 0005 <gen>)))
    • Game - Display to (Player group((Triggering player))) for 60.00 seconds the text: ...
    • Game - Display to (Player group((Triggering player))) for 60.00 seconds the text: ( + FinalCode)
    • Trigger - Turn off (This trigger)

• Load
  • Events
    • Player - Player 1 (Red) types a chat message containing -load as A substring
  • Conditions
    • (Substring((Entered chat string), 1, 6)) Equal to -load
  • Actions
    • Set FinalCode = (Substring((Entered chat string), 1, (Length of (Entered chat string))))
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Substring(FinalCode, 7, (Length of (Entered chat string)))) Equal to CusValCode
      • Then - Actions
        • Wait 0.30 seconds
        • Unit - Replace Paladin 0005 <gen> with a Paladin using The new unit's default life and mana
        • Selection - Select (Last replaced unit) for Player 1 (Red)
        • Wait 1.00 seconds
        • Unit - Set the custom value of (Last replaced unit) to (Integer(CusValString))
        • Trigger - Turn off (This trigger)
      • Else - Actions
        • Do nothing

Another question: do i need to have like a game cache sort of thing in order for this to work?

thanks.
