7segment decoder

Okay it made sense,

but I still have this syntax error:

Error (10511): VHDL Qualified Expression error at Lab5.vhd(51): integer2SevenSegment type specified in Qualified Expression must match std_logic_vector type that is implied for expression by context

as the output would be a signal should I then change my function to sth like this:

function integer2SevenSegment(i: in integer range 0 to 15) return

sevenSegment is

variable segment: sevensegment;

begin

case i is

when 0=> segment <= "1111100";
