what am i supposed to be doing...? (NumberSequence)

i REALLY need someone to explain this to me,

workspace.Bubba.Torso.ParticleEmitter.Size = NumberSequence.new(.1,1.5)

im trying to make it so it starts small and gets bigger

EDIT: it only uses the last number, it doesnt transition it

It doesn't only apply the last number, its just the sequence goes so fast. Heres a better way:

for i = 10,150 do	
--this for i statement repeats the code below over again
--until 10 through fifteen replace the variable i in the
--code below
Workspace.Bubba.Torso.ParticleEmitter.Size = i/100
wait(0.5) --change this to how ever long you want
end

****That means that the Particle emmiter's particle size starts at a size of .1, and proggresses to 1.5..

Ask me any questions!
