I'm not envisioning what you're trying to do, but you just need to compare your timefield with now(), might need to use timevalue() too

Hey guys thanks for responding, but I am going to let this one go. Nobody is suggesting or complaining. Thanks anyway.

Hi Mark
I agree, more info is needed, but why are you using 3 dropdowns instead of 1?

John

I'd have a Default Value set to Now() so when the record is created and someone picks from the dropdowns then you can compare the two.

Or if you need to update after changes have an After Update that sets the field.
You could either make the field ReadOnly and show on the Form, or just hide it if they user doesn't need to see it.

Hey Mark. You can build a valid Time value using TimeSerial. Put your combo box values into that. Not sure what you mean about the rest of it though. Perhaps some screen shots?

Hi guys, ok i left for several hours now I'm back and thanks for replying. So here is a screen shot. in the upper right corner are the three combo boxes. top is the hour middle that's open is the minutes and bottom is the am/pm. I am going to watch the video of timevalue and the others that you suggest. The if statement possibly is too long. So I think i'm deciding to use two more combo boxes. the hour and minutes and leave the am/pm alone. Sorry no screen shot for that. example. that start time will have the first two for the am. then the other two for the pm. Compare if the time is before 12pm then the am part is visible. after 12pm the pm part is visible and the am is hiding.  This is the best I can explain it.

Gentleman the matter is solved. On the way to my second job where the database is. Instead of having any code I thought of just adding to the minutes dropdown menu the minutes 1 - 60 am and pm both, and get rid of the am/pm. Thanks for helping.
