Two different objectives that affect (or effect? I never learned) the outcome
I'm clueless about what ljoy should do for the best, so I'm glad others have been able to advise, but this I do understand :-)
Both "affect" and "effect" can function as both nouns and verbs, but they have importantly different meanings. Here are some correct sentences.
This factor affects what happens. (That is, it makes some difference to what happens.)
This action effects a change in attitude. (That is, it causes a change in attitude, all by itself: remember this by noticing that it means the action is effective!)
The effect of this action would be that everyone would clap.
The affect of this piece of music is sadness. ("Affect" here means mood or emotional attitude; it's a much more technical and rarer sense than the others. It also has, in my dialect at least, a different stress from the others - I put the stress here on the first syllable, whereas for all the others I stress the second syllable.)
