Need help figuring out the trigger to increase a unit's max health

I hope someone reads this cause I haven't had any help for any of my posts and it's been getting me angry. Second, can someone please help with the GUI?

GUI code

function Trig_jass_attempt_Conditions takes nothing returns boolean
if ( not ( GetSpellAbilityId() == 'A01F' ) ) then
return false
endif
if ( not ( GetUnitAbilityLevelSwapped('A01F', GetSpellAbilityUnit()) == 1 ) ) then
return false
endif
return true
then (take(CastingUnit(+500Hitpoints(
endfunction

function Trig_jass_attempt_Actions takes nothing returns nothing
endfunction

//===========================================================================
function InitTrig_jass_attempt takes nothing returns nothing
set gg_trg_jass_attempt = CreateTrigger( )
call TriggerRegisterAnyUnitEventBJ( gg_trg_jass_attempt, EVENT_PLAYER_UNIT_SPELL_CAST )
call TriggerAddCondition( gg_trg_jass_attempt, Condition( function Trig_jass_attempt_Conditions ) )
call TriggerAddAction( gg_trg_jass_attempt, function Trig_jass_attempt_Actions )
endfunction

I'm not very good at any coding and any help would be appreciated. Even if your really just guessing. I want to add 500 health (800 for level 2) to my unit for 20 seconds when the 'war cry' ability is used thx in adv advance.
UPDATE: apparently it's possible to increase a unit's max health with a dummy. Not exactly sure how to this though any tips?

Why you convertved to JASS? Also you need to use a dummy ability to increase the health and then remove it after a certain time.

Dude. You converted it to Jass.

Just use

• tags and copy and paste the trigger as text from your WE (right click the trigger in the bottom right pane)

Don't worry I always save an extra copy of my trigger when I convert to jass. Therefore, I can just delete the jass trigger and enable the copy trigger. Unfortunately I'm not sure what ability increase your max health. Any help?

Basically an item ability that you have to fit your ability description and add/remove it.
