Math Error Costs Schools $3 M.

Ouch!

An accounting error apparently led the state to give 17 counties too much money for their school systems. The mistake could total $31 million, says an AP report posted on WJZ's Web site.

State officials estimate they overpaid Anne Arundel County schools by $5 million for the current school year. Overpayments totaled $3 million for Howard County schools, $2.5 million in Charles, $2 million in Frederick, $1.5 million in St. Mary's, $1 million in Calvert and less than $100,000 in Prince George's.
