You should know a structure of citric acid. As far as I know it is missing in http://www.chemicalforums.com/index.php?page=molecules

Acid + Base = Salt + Water

Citric acid is a tricarboxylic one and can react with 1, 2 or 3 molecules of NaOH.
The best wat to write its formula is
H3C6H5O7

Cirtic acid: H2C(COOH)C(OH)(COOH)CH2(COOH)

Now, think about the reaction between HCOOH and NaOH....
What could happen if you have more COOH groups?

H3C6H5O7 + NaOH = NaH2C6H5O7 + H2O
NaH2C6H5O7 + NaOH = Na2HC6H5O7 + H2O
Na2HC6H5O7 + NaOH = Na3C6H5O7 + H2O

or
H3C6H5O7 + NaOH = NaH2C6H5O7 + H2O
H3C6H5O7 + 2NaOH = Na2HC6H5O7 + 2H2O
H3C6H5O7 + 3NaOH = Na3C6H5O7 + 3H2O

And there I was trying to give hints instead of giving away the answer...
