Notebook Logic Error

posted

Hi guys, I am extremely new to Quantopian and am currently facing some issues with my code:

fundamentals = init_fundamentals()

free_cash_flow_yield = (fundamentals.cash_flow_statement.free_cash_flow)/(fundamentals.valuation.enterprise_value)

COC_Proxy = (fundamentals.income_statement.interest_expense)/(fundamentals.balance_sheet.long_term_debt)

please_work = get_fundamentals(query(fundamentals.valuation_ratios.ps_ratio)
.filter(fundamentals.valuation_ratios.ps_ratio 0.026*3)
.filter(fundamentals.operation_ratios.roic > COC_Proxy)
.filter(fundamentals.company_reference.primary_exchange_id.in_(['NYSE','NAS'])
.limit(100),
'2017-04-02')
please_work.head()

This error message shows whenever I run it
