AngularJS JSON value comparison

[Robert Bee]

Hi

I am trying to compare the weekly revenue figures and show, via an up or down arrow, whether they have increased or decreased.

The code line is: 

  <td>{{ x.ThisWeek }}&nbsp;<img ng-src="{{ x.LastWeek<x.ThisWeek && 'Images/green.png' || 'Images/red.png'}}"></td>
    <td>{{ x.LastWeek }}&nbsp;<img ng-src="{{ x.Week2<x.LastWeek && 'Images/green.png' || 'Images/red.png'}}"></td>
    <td>{{ x.Week2 }}&nbsp;<img ng-src="{{ x.Week3<x.Week2 && 'Images/green.png' || 'Images/red.png'}}"></td>

The results are mixed, see attachment (errors in yellow), but ultimately wrong. I have tried parsefloat for the week values but the results are worse.

Any pointers for an Angularjs beginner would be appreciated.

Many Thansk
