Newbie needs help creating database using SQL+ Worksheet

I'm trying to create my first database using SQL+ Worksheet for a CD collection. My first table, "artist", and 2nd table, "reclable" have only primary keys, no foreign key. The 3rd table, "catelog", is where I get stuck. When using this create statement:
CREATE TABLE Catelog
CatNum DECIMAL(4,0) primary key,
Title CHAR(50) not null,
Genre CHAR(2),
foreign key (labelcode) references reclabel,
check (CatNum > 0),
check (Genre in ('AR', 'BL', 'C', 'JZ', 'P', 'RB', 'RK', 'RP')))
;

I get this error:
foreign key (labelcode) references reclabel,
*
ORA-00904: invalid column name

labelcode IS a valid column name in reclabel. When using command: describe * reclabel
results are:
NAME
LABELCODE
LABELNAME

I don't understand what I'm doing wrong. I have a feeling I'm missing something very basic, but I don't know what it is. Please help before I pull out more hair that I can't afford to lose!

Thanking you in advance for your time.

try this...........
create table catelog
(
LableCode char(4) not null,
CatNum number(4)primary key,
Title char(50) not null,
Genre char(2),
foreign key(LableCode) references Table2_name(reclable)
)

Thank you so much! That worked.
