That "Ola" looks good. What would "dabas" be? Second person singular of "dare"? It's present tense, so not "gave" but "give". Neither it's imperative. I'm a bit confused who gives what and to whom. 
If someone gives "ola" to "anchiton", or "anchiton" to "ola", or "anchiton" gives "ola" to someone else, then would not some preposition be appropriate here?
