Error Assigning binary literal to ufixed

[Altera_Forum]

Hi guys, 

 I have been writing a ROM that I step through using a simple counter. Up until now the output of the ROM has been unsigned(9 downto 0), and assigning binary literals in the form "1111100000" has been working fine.  However I decided that I might want to try with unsigned fixed point with the same total width as in the unsigned case ie ufixed(7 downto -2). see attached file...  Now my understanding is that it shouldn't matter how the literals are assigned, so I haven't changed the literal values at all.  However I get the following errors:  Warning (12001): Port "oDAC_DATA[8]" does not exist in entity definition of "DDS_ROM". The port's range differs between the entity definition and its actual instantiation, "DDS_ROM:inst2". Warning (12001): Port "oDAC_DATA[9]" does not exist in entity definition of "DDS_ROM". The port's range differs between the entity definition and its actual instantiation, "DDS_ROM:inst2". Error (12009): Node "DAC_DB[9]" is missing source Error (12009): Node "DAC_DB[8]" is missing source Error: Quartus Prime Analysis & Synthesis was unsuccessful. 2 errors, 5 warnings  Error: Peak virtual memory: 869 megabytes  Error: Processing ended: Wed Jun 08 21:41:52 2016  Error: Elapsed time: 00:00:20  Error: Total CPU time (on all processors): 00:00:41 Error (293001): Quartus Prime Full Compilation was unsuccessful. 4 errors, 5 warnings   Could someone please enlighten me as to where I may be going wrong please... thank you
