Reconciling Deposit Acct Bal and Prepd Ord./Deposit

SUGGESTED

I just ran an Integrity Summary for a client of mine and everything matches except for the Deposits.

Dep Bal Balance $60778.90

Prep Ord/Deposit $57379.30

I don't know why but I am at a total loss at the moment as to how to fix this.  I took over these books from someone else.  Due to the amount of work I needed to do I didn't run this check at the time I took over the books so I don't know if this is an error from the last fiscal year or if it predates this.  

thanks
