Please help with "check" syntax

[Aaron P. Martinez]

I am trying to set up a table from a script that came with some software
"Value accounting/CRM" and i'm getting a few errors, one of which i
can't seem to figure out/fix.  

My system is RH 3.0 ES with mysql-server-3.23.58-1.  I have innodb
tables configured with the following statement in my /etc/my.cnf:
innodb_data_file_path = ibdata1:10M:autoextend
set-variable = innodb_buffer_pool_size=70M
set-variable = innodb_additional_mem_pool_size=10M
set-variable = innodb_log_file_size=20M
set-variable = innodb_log_buffer_size=8M
innodb_flush_log_at_trx_commit=1


The create table statement is below followed by the error.  

create table ItemSalesTax (
         STYPE      integer not null primary key,   /* STax Type */
         SDESC      varchar(35),
         SPERC      numeric(13,4) zerofill not null /* Percentage */
                    check(SPERC >= 0),
         SCONUM     integer not null,
         SYRNO      integer not null,
         SLEVEL     varchar(4) not null, /* Access Control Level */
         constraint staxlevel_ck
                    check (SLEVEL in ('READ','RW','DENY')),
         constraint STax_fk foreign key (SCONUM, SYRNO)
                    references AccYear(ACONUM, AYEARNO)
        );



ERROR 1064: You have an error in your SQL syntax near 'check(SPERC >=
0),
         SCONUM     integer not null,
         SYRNO      i' at line 9

I am not great w/mysql but gradually learning.  I have looked in the
online manual and can't find anything that helps.
I would really like to get this going as soon as possible to
evaluate...any and all help is GREATLY appreciated.

Thanks,
