Apologies if this has been covered, but I couldnt find it in a search.

Can I add a simple validation to WFB, eg say I have 2 dropdown boxes, one with Start Time , other with End Time.

Can I validate that the Start Time is before the End Time.... same sort of thing with start date and end date.

cheers all,
Mike

Really depends on how much control you need. The date has the "Allowed Dates" in the properties tab. Use one for the start and one for the end. The time may need a different approach. A regular expression would work, or make a drop down for the start only have times before the end. A little condition logic could also be used here.

As a thought if you have a start time box and a duration drop down then the finish time is always behind
