if you can please tell me how to fix this

Here's a tip that I use - if you open anything (if statement, function, parentheses, etc) instantly close it. Then you can type inside it knowing that you won't forget to close it. Pico-8 has a trick for this as well: type "function my_function()" or "if bool then" or "while bool do" and then press SHIFT + ENTER. This auto-completes the statement and moves your cursor inside it so you can start typing.

If there appears an UNCLOSE error, it's usual that you forget to add an end in the if, loop or function blocks. And yeah, that's what I often meet when I try to run my demo cart.
Look at the code below and you'll figure out where you forgot an end.
function _update()
dx=dx*air_res
dy=dy+g
x=x+dx
y=y+dy
if y>(floor-r) then
dy=-(dy*elastic)
y=(floor-r)
end
if x<r then
dx=-(dx*elastic)
x=r
end
if x>(128-r) then
dx=-(dx*elastic)
x=128-r
--mouse check
if stat(32)==x then print("aaaaaaaaa")
end
