could someone tell me when to use other or another?
Yes, it helps. But appart from that, I thought that another could be used only before singular countable nouns or before few+noun and that other could be used before singular or plural nouns, countable or uncountable. Is that right?

1) 'Another' is the indefinite article before 'other'. ALONE, it may be used before a singular countable noun ONLY.
2) Before certain adjectival quantifiers ('few', 'number of', 'quantity of',...), it may be used with a plural noun or an uncountable noun. Not all of these quantifiers may be used with uncountable nouns though.
3) In all other cases, 'another' may not be used.
