You forgot to pass the actual string to your sub functions.

 local function encrypt(str) local t = string.reverse(str) local ln = string.len(t) local lh = ln/2 local lho = lh+1 local aa = string.sub(1, lh) --returns the string "1" subbed from lh local ab = string.sub(lho, ln) --returns iho, which is ih+1, subbed from in local encrypted = ab..""..aa return encrypted
