PL/SQL Block

Hi I have a table t1(c1 number,c2 number,c3 varchar2(10),c4 number,c5 varchar2(10))
I have a procedure bmf_insert.
I need to write a block wherein I select the values from table t1 and then call the procedure bmf_insert.
The procedure bmf_insert inserts values into a table bmf the structure which is below.One of the values tracking_id in the table bmf is the max value from another table seq_num.
How can I write a pl/sql block such that I select the values from table t1,the max tracking_id from table seq_num and execute the procedure bmf_insert?
