How to make an upgrade researchable more than once?

[Ingvarr23]

Hello , i have found a market model online , successfully imported it into the game , created the building... I am trying to create a market that would function like this..

It would have upgrades {buy resources buttons , that would increase one resource while decreasing the other one} However I am not able to research an upgrade {buy wood for example} more than once so I can only perform the action one time. {buy wood} Any solutions?

This seems like a really weird use for upgrades. You may want to try making a size 0 unit and set the resource costs on the unit to negative for the ones you want to make more of and maybe give it 0 health so it dies instantly. You can buy any number of units of course so you can do it as much as you want.

Thanks I will try that, but I still have a problem, unit model?

Edit- It crashes , when I try to train my unit? Why?

duble edit - managed to get around that but now , my unit does not die instantly {gave 0 hp to it... } It is invincible!
