Hi Team,

I use this formula in screener, now I am trying to replace the "HK" here with a pre-defined items.

Economic_Sector,err = ek.get_data('SCREEN(U(IN(Equity(active,public,primary))/*UNV:Public*/), IN(TR.ExchangeCountryCode,"HK"), CURN=USD)',

'TR.TRBCEconomicSector',

{'Sdate':start_date,'Scale':scale,'Curn':curn})

For example:

I set country_code='HK'

and put the country_code into the formula, like this:

Economic_Sector,err = ek.get_data('SCREEN(U(IN(Equity(active,public,primary))/*UNV:Public*/), IN(TR.ExchangeCountryCode, country_code ), CURN=USD)',

'TR.TRBCEconomicSector',

{'Sdate':start_date,'Scale':scale,'Curn':curn})

Do you have idea why it doesnt work and how should I correct this.

Here is the error message:

Thanks!
