Limit DesiredAngle Motor6D with mathrandom?

I want to limit the math random for a motor desired, This is a wait script whichw ill will operate mathrandon run

However, i want to limit the Motor6D Desiredangle between 0.03 & 0.07, But i get this error:

18:52:38.212 - Workspace.Plane.Parts.WNGF_Model.HighAltitude_Wingflex:18: bad > argument #1 to 'random' (interval is empty) 18:52:38.212 - Stack Begin 18:52:38.213 - Script 'Workspace.Plane.Parts.WNGF_Model.HighAltitude_Wingflex', Line 18 18:52:38.213 - Stack End

b = script.Parent.Parent.Engine
wingflex = script.Parent.Parent.Wings_Motion
--LeftWingCenter.A.Motor.DesiredAngle = (math.random(MinimumFlex,MaximumFlex

LeftWingCenter = wingflex.Left.Outboard
RightWingCenter = wingflex.Right.Outboard

local MotorAngle = (0.03/0.07)

while wait(0.009) do	
	if b.Position.Y > 1 and b.Position.Y < 9999 then
		print('WingFlexing')
		LeftWingCenter.A.Motor.MaxVelocity = 0.005
		RightWingCenter.A.Motor.MaxVelocity = 0.005
		for x = 0.1,1 do 
   		 wait(math.random(1,2)) 
			print('WingFlex Motion 1')
   		 	LeftWingCenter.A.Motor.DesiredAngle = (math.random(MotorAngle))
			RightWingCenter.A.Motor.DesiredAngle = (math.random(MotorAngle))
			end
	end
end

randomNum =math.random (3,7) *.01 0 Also for math.random() you need two numbers. on lines 18 and 19 you have 1 number only

There was an error in the index table at line 17 heres a fix

Part = {} --This is a table where your part instance will go when it's created. 
Part.__index = Part --metamethod, that creates variables for you when you're referring to a variable and it doesn't exist. don't have to worry about what this line does really.

--by calling this function (called a constructor function), you will make a new part object/instance
call this function by saying: myPart = Part.new()
function Part.new(position)
    local newPart = {}
    setmetatable(newPart, Part)
    newPart.Transparency = 0
    newPart.Position = position --if you specified a position, you can set the part's position variable here

    return newPart --returns the part instance you just made into myPart variable 
end

--a method for the part class. you can call this by saying Part:SetTransparency(newTransparency)
function Part:SetTransparency(newTransparency)
    self.Transparency = newTransparency
    --This is where self comes in. the INSTANCE's transparency variable is set to the new transparency.
end
