[JASS] need help replacing abilities

[~DietX~]

spell 1:

the hero does something for 3 sec and after that the first spell is replaced by spell 2.
spell 2:
the hero makes an explosion and after that spell 2 is replaced by spell 1.

now the problem is that while the hero has spell 2 he can relearn spell 1 again because it was removed.

i'm thinking of making a connection spell.
A spell that can be learned but is invisible after you learn it and each time the player spends skill point on that spell spell1 and spell2 will gain lvls.

if i want to create a connection spell do i need to make a trigger that works every couple of seconds and checks if the connection spell was learned or can i do it otherwise?

and is there even a need in a connection spell or can i fix the problem without it?

if you dont understand me please tell me and i will edit my post, thanks for any kind of help

If the player can only have 1 of that type of hero, you can Enable/Disable the ability.

Else, you can just add/remove it with triggers. (You seem to forget to readd it )

i do add / remove
here:
call UnitRemoveAbility(u,'A043')
call UnitAddAbility(u,'A03U')
call SetUnitAbilityLevel(u,'A03U',level)

thats not the problem
the problem is when the hero has the second spell which isnt on his ability list he can relearn the deleted spell which is on his ability list...

Oh, yeah, you can't remove/add abilities to the Hero Abilities list.

In which case, Disable/Enable the ability (only works if the player can only have 1 of that ability at a time)

Thanks
i already made a connection ability and it works nice
what i mean by connection spell is a spell that does nothing but is on the hero ability list and the other 2 spells are connected to him.
