Yes. Don't just pick off the the difference in accounts from your cfs and put them in your b/s and i/s. Reconcile every single account. Do a Retained Earnings schedule to double check you net income and dividend amounts.Don't just plug in a number to the R/E account to balance the cfs.
If you are told that you sustained a 4500 loss from the sale of an asset, you need to deduct the fmv of the asset, and acc. amortization as well from the b/s.
Non cash transactions such as purchasing land by issuing shares will not show up on the csf, but remember to include them on your b/s and i/s.

Good Luck
