How To Add To Value Of Int Value That's Divided? [EDITED]

So this script won't work and idk why. It prints everything, but it doesn't add to the IntValue. It's suppose to add 'number of chickens multiplied by(*) 0.25' to the 'money value' but it doesnt. What am I doing wrong??

Works! :D New Script:

while true do
	local waitTime = script.Parent.WaitTime.Value
	local money = script.Parent.Parent.Money
	local chickens = script.Parent.Parent.Chickens	
    print('1')
    wait(waitTime)
    print('2')
    money.Value = money.Value + (chickens.Value*0.25)
end
