How much should I ask for as an Accounts Payable Clerk/Lead?

I may be hired after working as a temp fora couple months. My recruiter asked my salary and I told him I wasn't sure. I had a general idea but I didn't know what was much too or too little so I pretty much said I didn't know atm. I know that wasn't a great answer but I didn't want to undersell myself and didn't want to oversell myself either.
