Nope - but so long as you are comfy with code and events you will do fine.
You have two things to think about -
fires everytime the timer "goes off"
TimerInterval (in milli seconds) is how long between timer events
(where 0 turns the timer off entirely).
So - as missinglinq put it - set your timer interval to 3000 and your timer event
will fire every 5 mins.
Not much more to it
You can look at the Access VBA help entry but you won't find much more there.
