Is it possible to check how many of the boolvalues in a folder is true?

Basically, I have a folder with boolvalues of whether a player can craft a certain object, and i want to know how many of the values are true so I know how to organize the GUI.

#2 
local isTrue = 0
local boolFolder = --define the folder
for i,v  in pairs(boolFolder:GetChildren()) do
    if v:IsA('BoolValue') then
        if v.Value = true then
            isTrue += 1
        end
    end
end

I created a function in which you can use to find the number of True Bool Values, this will give you a table of the True Bool values as instances.

local function Check_For_True_Bool_Values(FolderObj)
	local NTBT = {} -- the table
	
	for i,v in pairs(FolderObj:GetChildren()) do
		if v:IsA("BoolValue") then--Some checking.
			if v.Value == true then--More checking.
				table.insert(NTBT, v)
			end
		end
	end
		
	return NTBT
end


local NTBT = Check_For_True_Bool_Values(workspace.Folder) --NTBT is the table
--worspace.Folder is the placeholder for the location to check the bool values in.


print(NTBT) --prints the table of the true bool values in the output.
print(#NTBT)--prints the number of true bool values in the output.

You can find the number by putting # before the table. In the first parameter of the function, set it as the folder with the bool values. Hope this helps!

You put True instead of true, might wanna fix that

local isTrue = 0
local boolFolder = --define the folder
for i,v  in pairs(boolFolder:GetChildren()) do
    if v:IsA('BoolValue') then
        if v.Value == true then
            isTrue += 1
        end
    end
end

OP will also need to change = to == for comparison.
Even better would be to remove the comparison altogether - comparing a boolean to a boolean is redundant. You can just do if v.Value then.
