I am having problems with this portion:

--allow a valid NMSR Date to be inserted
if (@srdate is not null) and (@srcompletedate is null) and (@nmsrdate_delete is null) and (@nmsrdate is not null) and (@nmsrdate >= @srdate and @nmsrdate <= @currentdate)
      begin
            
            update [Service Database] set [NMSR_Date] = @nmsrdate_delete where [Service Report No] = @srnum
    end

When I try to change the current NULL value for the NMSR_Date column for that record to any date, the value return back to NULL when it should have taken the new value for the date.

Please help.  Thanks.

Look at your condition again. It only runs if @nmsrdate_delete is null (line 3 of the listing below). And, if that is so, it sets NMSR_Date to @nmsrdate_delete (which is what it was before the trigger was activated!)

	if 	(@srdate is not null) 
		and (@srcompletedate is null) 
		and (@nmsrdate_delete is null) 
		and (@nmsrdate is not null) 
		and (@nmsrdate >= @srdate and @nmsrdate <= @currentdate)
	begin
		--raiserror (50009,11,1) with nowait
		update [Service Database] 
			set [NMSR_Date] = @nmsrdate_delete 
			where [Service Report No] = @srnum
    end
