Perplexed on My PLSQL

Hi Folks

Regarding DBMS_STATS.get_column_stats

I have been trying to figure out what is wrong with my code and do not see the issue regarding the difference between the code that runs fine and the code that errors out.

When I put the code on one line it runs just fine but when i break it up into seperate lines it errors out

I know it must be something simple, but I can't see the problem

Any assistance is appreciated

DECLARE
   n_distcnt          NUMBER;
   n_density          NUMBER;
   n_nullcnt          NUMBER;
   rec_srec           DBMS_STATS.statrec;
   datevals           DBMS_STATS.DATEARRAY;
