Error (10528): VHDL error at lcd.vhd(135): value "0" is outside the target constraint

I had upload a vhd file, please help me check. The error is at the line 135 : signal lcd_cmd_ptr : integer range 0 to LCD_CMDS'HIGH + 1 := 0; I have no any idea about it. Please help me solve...

try giving LCD_CMDS a specified range, or change the LCD_CMDS_T to natural range instead of integer.
