Help on a function "name" error

These are the custom script functions i have:

function GetStoredIntString takes handle h, string s returns integer
return GetStoredInteger(Cache(),I2S(Handler( h )), s)
endfunction

function StoreIntString takes handle h, string s, integer x returns nothing
call StoreInteger(Cache(),I2S(Handler( h )), s, x)
endfunction

and this is what i want to do:

this is a function called "Test", i deleted the rest of the triggers cuz i only need help with this line.
im trying to get an integer using those functions..
but i keep getting an "Expected a name" error:

call UnitDamageTarget(gg_unit_E00L_0043, t, GetStoredIntString(gg_trg_Test, "damage"), false, false, ATTACK_TYPE_NORMAL, DAMAGE_TYPE_UNIVERSAL, WEAPON_TYPE_WHOKNOWS)

t is already defined as a unit
i is defined as a certain integer i already defined
gg_trg_Test is this in a different function:

set gg_trg_Test = CreateTrigger()
call TriggerRegisterUnitInRangeSimple( gg_trg_Test, 128 , t )
call TriggerAddAction( gg_trg_Test, function Test )
call StoreIntString(gg_trg_Test, "damage", 15 + (35 * i))

why in the heck wont it work?!
i tried to defined "damage" as an extra local real but it still would give me the error.

any ideas?
