Hi, here is a work out:
> : rectangles in the block
>> : Block/Give Unit/etc related to the previous block

Create an Event, then switch to execute tab.
Block
>Condition: Count(LookoutTower)=1
>>Give Tech

You can also set the condition in the schedule tab and create a single block with the given tech only in the execute tab.

In order to avoid the player to research the tech:

Create an other Event.
Block
>ExecuteCode: ApplyRules("YourTech GoldCost = 100000");

Hopeflly it will help.

hm. So this will give me what I want? i'll post what it looks like on my side. currently

[Scheduling] >ID Optics
Start time 0h
Condition (Count(LookOutTower)==1)

[Script]
{Block}
>ApplyRules:("Sniper WatchRange +3; SniperAttack ActionRange +3; SniperAttackVeteran +3")
>ApplyRules:("Ranger WatchRange +3; RangerAttack ActionRange +3; RangerAttavkVeteran ActionRange +3")
>ActionRules:("SoldierAttack ActionRange +3; SoldierAttackVeteran +3")

this currently makes it so that "If there is 1 LookOutTower built, give Range Bonus to Units(sniper, ranger, soldier)"

I want this: "If LookOutTower research is complete, Give Range Bonus to units). and your work out will do that?

I would suggest you to remove the space after ; and add a space after the symbol +. The game can be sensitive to that.

Here is the spread sheet that Chabz made. This summarizes all the values in the game, hopefully, it will help you.

In your case, maybe Count(TechLookoutTower) = 1 could work. I'm not sure though as I never dealt with the research in the game.

@KarEssMoua
Yes, I tabbed the srpeadsheet, it has been helpful.

I'm just following the guide on <Operator><Value>, it isn't spaced (+3).

[condition] (count(TechLookOutTower)=1) does not work, it gives me an "Unknown Variable" popup. same with double '='

I am pretty sure there is something possible to do with the researched tech. However, as I said, I never really tried to create a variable depending the upgrades, so you might have to find the word used to say to the game that this tech is researched.
