thank you
my function looks like this...is there anything wrong with it..
i did what you told me but it does not work..its gives me result of 0.
i know that the formula its calculating the times perfectly...
can you giveme a hand with this matter please


********************************************************************************
function result() && Function to calculate time diference
********************************************************************************
parameters hrs1, min1, sec1, hrs2, min1, sec2, timesec1, timesec2, finaltime, timediff, result

local answertime, endtime

Hrs1 = VAL(SUBSTR ( answertime, 1, 2 ))
Min1 = VAL(SUBSTR ( answertime, 3, 2 ))
Sec1 = VAL(SUBSTR ( answertime, 5, 2 ))

Hrs2 = VAL(SUBSTR ( endtime, 1, 2 ))
Min2 = VAL(SUBSTR ( endtime, 3, 2 ))
Sec2 = VAL(SUBSTR ( endtime, 5, 2 ))

Time1Sec = ( 60 * 60 * Hrs1 ) + ( 60 * Min1 ) + Sec1
Time2Sec = ( 60 * 60 * Hrs2 ) + ( 60 * Min2 ) + Sec2

TimeDiff = Time2Sec - Time1Sec

IF Hrs2 < Hrs1
TimeDiff = (Time2Sec+(86400)) - Time1Sec
ENDIF

finaltime = (TimeDiff/60)+ 0.1

IF finaltime < .6
finaltime=.5
ENDIF

result= round(finaltime,1)
&&store result to result
return result
EndFunc
