where statement question

I have serveral viewers where i need to show certian records based on 2 different fields, both are list fields.

I have accomplished this to some degree with where statement at top using AND or OR.

this works if field 1 is one selection and field 2 is one selection. say field 1 value is option 1 and field2 is option 3

my current where statements look like this and they both work

'where' => "section='2' AND type='Car'",

and

'where' => "section='trac' OR section='trail' OR section='equip'",

if i want to show on viewer all records that are field1 = option1 and field2 = option3 or option4 or option5 how do i accomplish that. and/or can i do it with code similar to that above.
