I keep getting the same syntax error when trying to run my game. I don't know if I'm missing something or not.
the code is:
if btn(x button) and p1.landed=true then
p1.y-p1.boost
p1.landed=false
p1.jumping=true
end

It kept giving me the error 'then' expected near '='

You need to use "==" (two equals signs) for comparisons. One equals sign is only used for assigning a value to a variable.

So your code needs to be:

if btn(x button) and p1.landed == true then
  p1.y-p1.boost
  p1.landed=false
  p1.jumping=true
end

Also "p1.y-p1.boost" should probably be "p1.y -= p1.boost" (subtract p1.boost from p1.y, updating p1.y)

ok got it, thanks!
