Here's the way I use platforms that work with scroll-x.

Along with a variable for scroll-x  , you will also want to put a variable just for the platform in called, "offset scroll-x", or something like that, and you will need a variable for all sprites called "motion". See, when something, is set to scroll-x, it goes to the center when the scroll x matches its "* ?" So you would put on this script for the moving platform. It depends on how long you want it so move, I'll just make it continually move back and forth 100 "scroll x-es". 

For the platform:

when gf clicked
set [offset v] to (0)
forever
set x to (((scroll-x) + ((480) * (0))) - (offset scroll-x)) 
end

when gf clicked
forever
set [motion v] to (1)
repeat (50)
change [offset scroll-x v] by (2)
end
set [motion v] to (2)
repeat (50)
change [offset scroll-x v] by (-2)
end
end

For the main sprite:

when gf clicked
forever
if <touching [platform v]?>
if <(motion) = (2)>
change [scroll-x v] by (-2)
end
if <(motion) = (1)>
change [scroll-x v] by (2)
end
end
end

The first two scripts place the platform as an offset of scroll-x, but since the offset is always changing, the platform appears to move, but with scroll-x. The last script simply makes the main character move along with the sprite. When moving right, changes scroll-x by -2, if left, 2. You can apply velocity to this, too.

Hope this helps!

EDIT: fixed the scripts up a bit

Thanks, although I think you may want to see the actual engine to get the clear problem 

AAA! Sorry, I don't really understand!       My way is all I can think of

It's okay. Thanks for trying. I guess i'll just be a lil' more basic with the x-moving platform. I'll give you a love it

I'm going to use it anyways, and I can't believe how basic it was, I should've thought of it   

Really?!
