Can you please elaborate?

I already figured that my original problem was a permission problem of some sort, so my new code is

TEXT TO lcSQL TEXTMERGE noshow
  DECLARE @MaxSize INT, @MaxSizeDesc varchar(10)
  SELECT @MaxSize = CASE WHEN SERVERPROPERTY('ProductVersion') > '10.5' THEN 10 * 1024 * 1024 -- 10GB for SQL Server 2008 R2 Express 
			ELSE 4 * 1024 * 1024 END,
		 @MaxSizeDesc = CASE WHEN SERVERPROPERTY('ProductVersion') > '10.5' THEN '10 GB' 
			ELSE '4 GB' END

  
   SELECT SUM(CONVERT (BIGINT, SIZE) * 8) AS SizeKB,
    @MaxSize AS MaxSize, @MaxSizeDesc AS MaxSizeDesc
	FROM sysfiles F WHERE status & 0x40 <> 0x40 -- Exclude log files
  ENDTEXT   
  mysqlexec(m.lcSQL, 'csrTemp', program())
  lcSpaceWarn    = ''
  
  select csrTemp
  if csrTemp.SizeKb >= .8 * csrTemp.MaxSize && 80% full

Now the failing line is the last one IF ...

Do you know what may be wrong here?

Thanks in advance.
