Oops! It looks like Task 1 is no longer passing

I am was able to complete task 1 of this challenge with no issue but when I attempt to check task 2 I get this error : Oops! It looks like Task 1 is no longer passing

js/app.js
// height and width of the svg
var height = 800, width = 500;
var padding = 50;

var viz = d3.select("#viz-wrapper")
    .append('svg')
    .attr('id', 'viz')
    .attr('height', height)
    .attr('width', width);

d3.csv('app/climate_data_truncated.csv', function(data) {

    dots = viz.selectAll('circle')
        .data(data)
        .enter()
        .append('circle');

    dots.attr('r', function(d) {return Math.abs(d.TMIN) / 10})
        .attr('cx', function(d) {return Math.max(0 + padding, Math.random() * width - padding)})
        .attr('cy', function(d) {return Math.max(0 + padding, Math.random() * height - padding )})
        .style('stroke', function(d){
              year = d.DATE.substring(0,4)
              if (year === "1973") {
                return "yellow"
            }
            else {
                return "#ff00f3"
            }
     });

        .style('fill', function(d) {
            year = d.DATE.substring(0,4)
            if (year === "1973") {
                return "blue"
            }
            else {
                return "#ff00f5"
            }
        });

That just means you have a syntax error.

Since a syntax error invalidates the entire code, and since it re-checks the tasks in order, it will typically give that message when you have introduced a syntax error.

In this case, it's because you are chaining functions, but have a semicolon between functions in the chain (right before the last ".style()").
