Mathmatical Multiple imputs, Help?

Alright, Last post people got pissy and acted up by downvoting the question. Let's try this again. So here is what I'm trying to do, when this block is touched by anything it adds one to it's number which is the name of the block. (So I touch it once it becomes 1, touch again it becomes 2, ect.) I had an issue where I lagged in studio while standing on it, it went to 22 and console didn't say "Ahh". I tried to fix this issue but the error I get on line 21 is "expected 'then', got '=' ", How do I fix this? (To clarify, This is so that I can have the name be anywhere from 20 to 24 and still have the console say "Ahh") [I do plan or relaying out the table for all the math() related functions to deal with larger numbers, so me doing something like {if script.Parent.Name == "20,21,22,23,24" then} will only temporarily fix the issue]

number1 = script.Parent.Name
number2 = 1;
number3 = 10;
number4 = 40;
number5 = 250;
number6A = 20 --Math()Start
number6M = 24 --Math()Max
number7A = 25 --Math2()Start
number7M = 29 --Math2()Max
number8A = 30 --Math3()Start
number8M = 34 --Math3()Max
number9 = 35 --Math4()

debounce = false

function math()
	number1 = script.Parent.Name
	number6M = 24
	number6A = 20
	number7A = 25
	if number7A = number1 or number1 > number7A then   --Error on this line
		math2()
	elseif number6A = number1 or number6A < number1 then
       print"Ahh"
	end
    end
end

function math2()    --C'mon me, fix up that math() already.
	number1 = script.Parent.Name
	number7A = 25
	number7M = 29
	if number6A = number1 or number6A < number1 then
		print"Hey"
	end
end

function math3()
	if script.Parent.Name == "30" then
		print"Alert"
	end
end

function math4()
	if script.Parent.Name == "35" then
		print"I am die"
		wait(4)
		script.Parent.Parent = nil
	end
end

function onTouched()
    if debounce == true then return end
    debounce = true
    number1 = script.Parent.Name
    print(number1+number2) 
    script.Parent.Name = (number1+number2)
    wait(0.2)
    print "Tick"
    math()
	math2()
	math3()
	math4()
    debounce = false
end

script.Parent.Touched:connect(onTouched)

Watch someone downvotes this because they want to be a jerk.
