Restarting numbering of citations at each section

Hello,

I have a word document (2007) with several sections.

I have succesfully finished section 1 with (30 citations) at the end of the section.

Now at the next section, i want to insert another citation from Endnote X2 and i would like it to start numbering at 1 and placed at the end of section 2.

Is it possible to do this? So far whatever i try it continues numbering (i.e start at 31) and it is placed in section 1.

Let me know the way to fix this.

Thank you,

CK
