Access a variable outside the scope of a Handlebars.js each loop

I am rendering this in an express app which uses handlebars as template engine:
res.render("movies", { data: pages, arraypages:arrayPages, movie:movie})
"arrayPages" is an array:
[
1, 2, 3, 4,
5, 6, 7
]
"movie" is a string like "top gun"
Inside the handlebars template there is:
{{#each arraypages}}
<form action="/getmoviepage" method="post">
<a>{{this}}</a>
<input type="hidden" name="{{movie}}" value="{{this}}">
</form>
{{/each}}
Which outputs:
<form action="/getmoviepage" method="post">
<a>1</a>
<input type="hidden" name="" value="1">
</form>
<form action="/getmoviepage" method="post">
<a>2</a>
<input type="hidden" name="" value="2">
</form>
<form action="/getmoviepage" method="post">
<a>3</a>
<input type="hidden" name="" value="3">
</form>
<form action="/getmoviepage" method="post">
<a>4</a>
<input type="hidden" name="" value="4">
</form>
<form action="/getmoviepage" method="post">
<a>5</a>
<input type="hidden" name="" value="5">
</form>
<form action="/getmoviepage" method="post">
<a>6</a>
<input type="hidden" name="" value="6">
</form>
<form action="/getmoviepage" method="post">
<a>7</a>
<input type="hidden" name="" value="7">
</form>
As you can see the "movie" variable is not rendered (the variable should render inside the "name" attribute). If I put the variable outside the "each" loop is rendered OK.
{{movie}} //This is rendered OK, outside the "each" loop
{{#each arraypages}}
<form action="/getmoviepage" method="post">
<a>{{this}}</a>
<input type="hidden" name="{{movie}}" value="{{this}}">
</form>
{{/each}}
How do I render a variable inside a "each" loop in handlebars?

Answer 1

Try
<input type="hidden" name="{{../movie}}" value="{{this}}">
The ../ path segment references the parent template scope that should be what you want.
