In the "group by", you missed fields Distance and [Origin State Code]

[maxgro]

with a group by

all non aggregated fields (in your example the fields without sum) must be in the group by section

so add [Origin State Code] and Distance to the group by (well, check also the other fields)

[Anonymous]

you can't write sum() in script like this without taking all the fields in account in group by statement. could you explain what you want to do or attach your app.

You also need to make sure that if your table name has spaces in it, it is between the square brackets ([My expression is])

Once you fix that there might be other things that might be needing a fix, but make that fix and let us know if it works or not.

Best,
