Hi
Put the following formula to calculate the seconds until the off in cell D2.
It shows a minus figure after the scheduled off.
Then simply use an IF statement in the trigger to fire at x or less amount of
seconds before the off that you require?
| Code: |
| =IF(LEFT(D2)<>"-",(HOUR(D2)*3600)+(MINUTE(D2)*60)+SECOND(D2),-((HOUR(SUBSTITUTE(D2,"-",""))*3600)+(MINUTE(SUBSTITUTE(D2,"-",""))*60)+SECOND(SUBSTITUTE(D2,"-","")))) |
Hope it helps - Michael  |
