How do you express an ionic and net ionic equation?

This is the equation - 3Ca(NO3)2 + 2Na3(P04) = 1Ca3(PO4)2 + 6Na(NO3)

I know how to balance it i just can figure out how to do an ionic or net ionic .

An ionic equation is a chemical equation in which the electrolytes are written as dissociated ions.  Ionic equations are used for a single or double replacement reaction that occurs in aqueous solutions.  A net ionic equation would be the ions involved that are part of the reaction and do not stay in the aqueous solution.  The ions that stay in the aqueous solution and are not part of the reaction are called spectator ions.  Ionic equations for this reaction would be as follow:

3Ca++  +  6(NO3)-  +  6Na+  2(PO4)---   --->  3Ca++  + 2(PO4)---  +  6Na+  6(NO3)-

For the net ionic equation, you would list the ions that do not remain in aqueous solution.  That has not been indicated here, so check and see if any of these ions remain in aqueous solution.  If not, this would be the net ionic equation, as it is a double replacement reaction.
