	    turtle.suck()

In the function, your argument is B but in the function you use a lower case b. That might be the prob,

another problem on line 38:
needs to be:

if recipe[message] then

that might work to fix your error

Also in your goBackHome function you use both lower and upper case b.

i changed part of my code using the "for k,v in pairs" and it worked much better.
those upper case and lower case B, where just html messing up the post… in my code they are all lowercase, that wasn't the problem.. it's just that im unable to reference the table values
