Create a function to convert to decimal hours, then use it in a SELECT - SQL to get the totals:

FUNCTION StringTimeToDecimalHours

LPARAMETERS ;
	tcStringTime

RETURN (3600 * VAL(SUBSTR(tcStringTime, 1, 2)) + ;
60 * VAL(SUBSTR(tcStringTime, 4, 2)) + ;
VAL(SUBSTR(tcStringTime, 7, 2))) / 3600

SELECT ;
	cPersonName, ;
	SUM(StringTimeToDecimalHours(cStringTimeField)) AS nHours ;
	FROM MyTable ;
	INTO CURSOR Results ;
	GROUP BY cPersonName
