Exception in template helper: Cannot read property 'name' of undefined - meteor

Question

I have been struggling with getting a userprofile to display for a specific user for some time now and I have been reasonably successful. I have ht oe problem where I get the error in the heading.
I publish a schools collection like this
Meteor.publish("schoolData", function () {
return Schools.find();
});
My subscription looks like this
Meteor.subscribe('schoolData');
My HTML looks like this
<template name="userProfile">
<title>My Profile</title>
<table>
<tr>
<td>User Name: </td>
<td>{{userName}}</td>
</tr>
<tr>
<td>First Name: </td>
<td>{{firstName}}</td>
</tr>
<tr>
<td>Last Name: </td>
<td>{{lastName}}</td>
</tr>
<tr>
<td>Registered E-mail: </td>
<td>{{email}}</td>
</tr>
<tr>
<td>Contact E-mail: </td>
<td>{{email}}</td>
</tr>
<tr>
<td>Phone Number: </td>
<td>{{phoneNumber}}</td>
</tr>
<tr>
<td>School: </td>
<td>{{schoolName}}</td>
</tr>
<tr>
<td>First year: </td>
<td>{{firstSchoolYear}}</td>
</tr>
<tr>
<td>Last year: </td>
<td>{{lastSchoolYear}}</td>
</tr>
<tr>
<td>Matriculated? </td>
<td>{{matriculated}}</td>
</tr>
<tr>
<td>House Name: </td>
<td>{{houseName}}</td>
</tr>
<tr>
<td>Country living in: </td>
<td>{{country}}</td>
</tr>
<tr>
<td>City living in: </td>
<td>{{cityOfResidence}}</td>
</tr>
<tr>
<td>Industry employed in: </td>
<td>{{emplIndustry}}</td>
</tr>
</table>
</template>
and the javascript looks like this
Template.userProfile.helpers({
email: function() {return Meteor.user().emails[0].address},
userName: function () {return Meteor.user().username},
firstName: function () {return Meteor.user().profile.firstname},
lastName: function () {return Meteor.user().profile.lastname},
phoneNumber: function () {return Meteor.user().profile.phone},
schoolName: function () {return Schools.findOne(Meteor.user().profile.schoolName).name;},
firstSchoolYear: function () {return Meteor.user().profile.firstschoolyear},
lastSchoolYear: function () {return Meteor.user().profile.lastschoolyear},
matriculated: function () {return Meteor.user().profile.matriculated},
houseName: function () {return Meteor.user().profile.housename},
country: function () {return Meteor.user().profile.country},
cityOfResidence: function () {return Meteor.user().profile.cityofresidence},
emplIndustry: function () {return Meteor.user().profile.emplindustry},
signedUp: function () {return Meteor.user().profile.createdAt},
});
I seem to get the Error
Exception in template helper: TypeError: Cannot read property 'name' of undefined
and it mees this is from the Schools collection.
Can someone help me spot my mistake please.

First of all, there is better way to do what you want to achieve- wrap all your html with {{#with user}} tags like this:
<template name="userProfile">
{{#with user}}
<title>My Profile</title>
<table>
<tr>
<td>User Name: </td>
<td>{{userName}}</td>
</tr>
<tr>
<td>First Name: </td>
<td>{{firstName}}</td>
</tr>
<tr>
<td>Last Name: </td>
<td>{{lastName}}</td>
</tr>
<tr>
<td>Registered E-mail: </td>
<td>{{email}}</td>
</tr>
<tr>
<td>Contact E-mail: </td>
<td>{{email}}</td>
</tr>
<tr>
<td>Phone Number: </td>
<td>{{phoneNumber}}</td>
</tr>
<tr>
<td>School: </td>
<td>{{schoolName}}</td>
</tr>
<tr>
<td>First year: </td>
<td>{{firstSchoolYear}}</td>
</tr>
<tr>
<td>Last year: </td>
<td>{{lastSchoolYear}}</td>
</tr>
<tr>
<td>Matriculated? </td>
<td>{{matriculated}}</td>
</tr>
<tr>
<td>House Name: </td>
<td>{{houseName}}</td>
</tr>
<tr>
<td>Country living in: </td>
<td>{{country}}</td>
</tr>
<tr>
<td>City living in: </td>
<td>{{cityOfResidence}}</td>
</tr>
<tr>
<td>Industry employed in: </td>
<td>{{emplIndustry}}</td>
</tr>
</table>
{{/with}}
</template>
And helper like:
user: function(){return Meteor.users.findOne({_id:Meteor.userId()});
Now you can use all data from your user collection in html without helpers
And to your question - you made your query wrong, it should look like this:
schoolName: function () {
return Schools.findOne({name:Meteor.user().profile.schoolName}).name;
},
I assumed you want to check school by name, if you have _id of it in profile.schoolName change name with _id
