Can someone help me to put the date and time field as one so that it shows as DD/MM/YY HH:NN in one field. I have the date and Time in two fields currently.
If your data is stored as date/time datatypes then you may be able to simply sum them. Access stores dates as integers and times as decimal fractions so date and time together is simply the sum of the two values. So:
[datefield] + [timefield]
