Oracle Group Group error

[Hollywood_Jack]

Peeps,
I'm getting an "ORA-00937: not a single group group function error" when I try and run the following query. Any help is appreciated:

I figured it out. In my second select statement, I had to add the following:

(SELECT fd.claim_carrie r_key,
min(case when fd.trn_category _cd='MEDBICL' and fd.TRN_RESERVE >0 then fd.eval_date else null end) med_rdate,
min(case when fd.trn_category _cd='INDPDCP' and fd.TRN_RESERVE >0 then fd.eval_date else null end) ind_rdate,
min(case when fd.trn_category _cd='EXPENSE' and fd.TRN_RESERVE >0 then fd.eval_date else null end) exp_rdate
FROM sti_data.scd_fi nancial_detail fd
group by fd.claim_carrie r_key) fd
where fd.claim_carrie r_key = tbt.claim_carri er_key
