My code is calling a function before the trigger does?

It's very confusing and only yesterday it was working fine.

local functionblock3 = game.workspace.FunctionBlock3
local AppearingBlock = game.workspace.AppearingBlock

functionblock3.Touched:Connect(function()
    local functionblock3 = "functionblock3 in use"
    print (functionblock3)
    AppearingBlock.Transparency = 0
    AppearingBlock.Cancollide = true
end)

The one I just copy and pasted is meant to call a function when the player touches a block, however when I test my game, the function is already called.

 local FunctionBlock2 = game.workspace.FunctionBlock2
local DissapearingBlock = game.workspace.DissapearingBlock

FunctionBlock2.Touched:Connect(function()
    local functionblock = 'function block touched'
    print (functionblock)
    DissapearingBlock.Transparency = 1
    DissapearingBlock.Cancollide = false
end)

This code calls a function when my character touches a block, again, it worked fine just yesterday but the function calls before I even step on the block.
