Serious problem with limiting Units because of Upgrades

[Cyrax86]

Hi!

I already tried to limit units with a dummie unit, but if I upgrade a unit, the upgraded unit is not on the map but the ''upgrade of this unit'' ...that means that the old one can be built again -and I cant prevent that(Not even with the standard trigger for unit limiting). Even with the dummie it becomes very complicated...

Does anyone know an easy trigger that solves my problem?
All ideas welcome, because if I cant fix this serious problem my whole map is ruined...

Short:
Something makes this problem quite complicated:
I have to limit an upgradeable unit which can be built 6 times...

uuuuhhh....

I don't get it. what IS the problem?

"Upgrade of the unit" like how towers upgrade, or like how you make researches?

Do you mean, like a total of 6 units of a single type can be built, and when they upgrade it it still counts as part of the limit?

First of all thank yu for the answer

I mean upgrading a unit likr a tower (no research)
And a total unit limit of e.g 6 in 1 map and for 1 player
