Why is this script not working?

I am making a zombie and have written in this script to make it follow me but it does not. I can push it around but no follow like I said. Here is the script to move:

while true do
	wait (.1)
	findNearestTorso()
	if target~= nil then
		script.Parent.Humanoid:MoveTo(target.Torso.Position,target.Torso) 
	end
end
	

What is wrong?

Assuming 'findNearestTorso return a target, that you want to follow.

while true do
    wait (.1)
    local target = findNearestTorso()
    if target~= nil then
        script.Parent.Humanoid:MoveTo(target.Torso.Position,target.Torso) 
    end
end

According to the code you provided, 'target' was nil so it technically never ran the line under it.
