Multiple where expressions

[#1]

I am having difficulty ensure that both where query are the same in an expression.

I am trying to do the below command and cant work out what I need to do to ensure both statements are true.

Sum ({$<[period_end]={'31/01/2014 00:00:00'} && [concept_id]={'242'}>} string_value)

Hey ,

Sum ({$<[period_end]={'31/01/2014 00:00:00'},[concept_id]={'242'}>} string_value)

BR,
