Do you know how I can resolve this error?

Incorrect syntax near '.'.

SELECT DISTINCTROW ImportMonthlyChecksEntity.amt1,

nvarchar is a Unicode character.  Think all of those Swedish letters that are not in the English A-Z alphabet.

Sum means you are trying to add a column of numbers.

Obviously you can't sum a bunch of characters.   SUM ( A + Z + WAHOO) = ??

If we're talking the Sum(amt2), and it is nvarchar, the obvious knee-jerk reaction is that if these are numbers (amt would imply amount) where you would want to do math operations, then the column should be some kind of numeric data type and not character data type.  Recommend changing the column data type.

If you can't do that then you could always SUM(CAST(amt2 as decimal(9,2))), but I reeeeeeeeeeeeeeeeeeeeeeeally recommend against that as any value that cannot be converted to a number will throw an error.

For starters, in these situations it would greatly help if you could place your code in a CODE block (comment toolbar), and when an error occurs double-click on the error, watch the cursor jump to the offending line, and tell us what line that is.

Looking..

By any chance did you copy this from Microsoft Access?   If so check out Migrating your Access Queries to SQL Server Transact-SQL, which is a handy conversion article I wrote.

Things that are errors..
  • DISTINCTROW is not a valid T-SQL function in 2008.  DISTINCT is.
  • FORMAT$ is not a valid T-SQL function in 2008.  
  • DATEPART('m' remove the single quote marks

Things that are not errors and highly recommended
  • Since this query only has one table name you can lose the tablename. reference in all of the column names.
  • Using DISTINCT and GROUP BY serve the same purpose and is redundant.  Recommend losing the DISTINCT.
  • [dateFile By Month] -->  Lose the spaces in column names, which force the developer to use square brackets [ ] to surround it, which is one thing to potentially forget and throw an error.

With all of the above..
SELECT DISTINCT 
	amt1, 
	DATENAME(month, datefile) + ' ' + YEAR(dateFile as char(4)) as dateFile_by_month, 
	branch, 
	Sum(amt2) AS count_amt2, 
	Count(*) AS count_all
FROM ImportMonthlyChecksEntity

Yes I did copy this from Microsoft Access and I will review your article St. Jimbo.  :)

Typo, my bad, did not include the CAST( before the year.
SELECT DISTINCT 
      amt1, 
      DATENAME(month, datefile) + ' ' + CAST(YEAR(dateFile) as char(4)) as dateFile_by_month, 
      branch, 
      Sum(amt2) AS count_amt2, 
      Count(*) AS count_all
