how to get data by finding all and finding one at the same time - meteor

Question

In my project on the user edit page I would like to show the current role,wich i get by findOne byId,but I would also like to get all available roles so that I can choose, roles are in a separate collection, and I dont have a problem when displaying eather one...or all..
<div class="form-group col-lg-12">
<label>Email</label>
<input type="email" class="form-control" id="email" value="{{emails.[0].address}}">
</div>
<div class="form-group col-lg-12">
<label>Password</label>
<input type="password" name="" class="form-control" id="password" value="{{password}}">
</div>
<div class="form-group col-lg-6">
<label>Name</label>
<input type="text" name="" class="form-control" id="firstname" value="{{profile.name}}">
</div>
<div class="col-xs-12"><strong>Current role:</strong>
<label class="radio-inline">
<input type="radio" name="optradio" id="accountRole" value="{{roleName profile.role}}" checked>{{roleName profile.role}}
</label>
</div>
{{/with}}
<div class="col-xs-12">
<form>
<div class="col-xs-12"><strong>Roles:</strong>
{{#each rolesInformation}}
<label class="radio-inline">
<input type="radio" name="optradio" id="accountRole" value="{{_id}}">{{roleName}}
</label>
{{/each}}</div>`
helpers look like this:
Template.editUser2.helpers({
user: () => {
return Meteor.users.findOne({_id:Session.get('id')});
},
playerInformation: () => {
return Players.find().fetch();
},
roleName: (id)=>{
return Roles.findOne({_id:id}).roleName;
},
rolesInformation: () =>{
return Roles.find().fetch();
},
when i run roleName or rolesInformation separateli it works fine...
whet both included i get "roleName not defined"
