I've successfully used other kinds of hidden array properties, but I am suddenly having trouble since I added a Form one

I'm only using this array within my script - it is not needed by the CK, hence I hid it .... but perhaps I should try it as a variable?
here's the top of my working script:
Spoiler ;=============== PROPERTIES ==========================================;Formlist Property ScarabDurabilityTrackerFLST AutoFloat Property DamagePerHit AutoFloat Property BaseDurability AutoFloat[] Property DurabilityTracker Auto HiddenActor Property ThisActor Auto HiddenWeapon Property RightWeapon Auto HiddenWeapon Property LeftWeapon Auto Hidden
And the non-functional one (it compiles but just doesn't work proper!
Spoiler ;=============== PROPERTIES ==========================================;Float Property DamagePerHit AutoFloat Property BaseDurability AutoFloat[] Property DurabilityTracker Auto HiddenForm[] Property FormTracker Auto HiddenActor Property ThisActor Auto HiddenWeapon Property RightWeapon Auto HiddenWeapon Property LeftWeapon Auto Hidden
I did read your thread, but it doesn't seem to apply to my usage as I am not populating mine from the CK...
