I'm not entirely sure what you're trying to do but see this code for a local variable that is a list. If this doesn't help then you'll need to give more specific information. 
 Note that I've used two different ways of referencing where I want things saved. They function exactly the same. 
 
 Quoted square brackets indexing (eg. local!valueList[fv!index]["username"]) 
 Dot notation (eg. local!valueList[fv!index].password) 
 
 a!localVariables(
 local!valueList,
 {
 a!forEach(
 items: local!valueList,
 expression: a!sideBySideLayout(
 items: {
 a!sideBySideItem(
 item: a!textField(
 label: concat(
 "Username ",
 fv!index
 ),
 labelPosition: "ADJACENT",
 value: index(
 fv!item,
 "username",
 {}
 ),
 saveInto: local!valueList[fv!index]["username"]
 )
 ),
 a!sideBySideItem(
 item: a!textField(
 label: concat(
 "Password ",
 fv!index
 ),
 labelPosition: "ADJACENT",
 value: index(
 fv!item,
 "password",
 {}
 ),
 saveInto: local!valueList[fv!index].password
 )
 ),
 a!sideBySideItem(
 item: a!richTextDisplayField(
 label: concat(
 "Delete row ",
 fv!index
 ),
 labelPosition: "COLLAPSED",
 value: a!richTextIcon(
 icon: "times",
 color: "NEGATIVE",
 link: a!dynamicLink(
 value: remove(
 local!valueList,
 fv!index
 ),
 saveInto: local!valueList
 )
 )
 )
 )
 }
 )
 ),
 a!richTextDisplayField(
 label: "Add new entry to list",
 labelPosition: "COLLAPSED",
 value: {
 a!richTextIcon(
 icon: "plus-circle",
 link: a!dynamicLink(
 value: {
 username: loggedInUser(),
 password: "password123"
 }
 )
 ),
 a!richTextItem(
 text: " Add new item to list",
 link: a!dynamicLink(
 value: append(
 local!valueList,
 {
 username: loggedInUser(),
 password: "password123"
 }
 ),
 saveInto: local!valueList
 )
 )
 }
 )
 }
) 
 You could also explore the a!map() function rather than creating a dictionary such as what I did in the "+ Add new item to list" saves (starting at lines 68 and 79)

In addition, all you need to do to define your local variable as a list is utilize {} in it's definition. Here's an example of saving into index 2 of an empty local!valuelist variable: 
 a!localVariables(
 local!valuelist: {},
 {
 a!richTextDisplayField(
 label: "List:",
 value: a!forEach(
 items: local!valuelist,
 expression: {
 a!richTextItem(
 text: concat("Item ",fv!index,": ",fv!item)
 ),
 char(13)
 }
 )
 ),
 a!buttonArrayLayout(
 align: "START",
 buttons: {
 a!buttonWidget(
 label: "Save",
 value: "B",
 saveInto: a!save(local!valuelist[2],{username: save!value})
 )
 }
 )
 }
)
