What is the actual code you have for non combo box fields. The code you have stated above gives an error.
Please post a screenshot clearly showing the EXACT code.

If you need to re-enter the same data into another record, there may be something wrong with the table design, because tables need "normalization," which means each piece of data only appears once in a table.  In a normalized design, you rarely need to enter the same data in different rows.

OK, here is a simple database that demonstrates the problem. There are two simple tables as shown in images 1 and 2. There is a simple form shown in image 4. If I want the ScanDate to remain on the form after I press Add Record, I go to the After Update property for the sheet, enter the code builder, and enter the code shown in image 3. This works.
However, if I want the TechName to remain, when I try to enter similar code, the code builder will not let me use the DefaultValue word in the code. I type in Me.TechName. but the only option there is value.
I hope this is clear enough. In my previous attempts to get an answer I also showed these screenshots, although with a more complicated database. This time I just wanted anyone who has been successful using a combo box and making the value remain after adding the record to tell me how they did it.
Thanks for helping.

Use the name of the Combo Box not the Field Name.

Entering data and then moving to a new record in that same table, then you'll need a way to copy the value from the previous record. Changing the default value like that isn't a good way to go about it. What you might want to consider doing is putting that Tech name field as a default value up in the form header like I cover in the Extended Cut for this video: Default Value.

Or you could use an unbound form and then add the data with an SQL insert statement when the user clicks the button but that's a little more involved.

I'd also like to remind you that even though you posted already in the Forum and no one's posted a reply, just sit back and be patient please because the moderators that help here are all volunteers and even though I do read all of the posts myself eventually I'm currently about 6 months behind due to the volume posts we receive. Tech support is not guaranteed and if you want paid support there is the Access Developer Network forum.
