[brendan_c23]

@sdetweil Yes I made that change, but the error was still coming up for me

[sdetweil]

@brendan_c23 show me those 10 lines

[brendan_c23]

@sdetweil //if another currency is required - usd is default
var differentCurrency = false;
if(that.config.currency.toLowerCase() != “usd”){
differentCurrency = true;
var requiredCurrency = this.config.currency.toUpperCase();
}

	for (var key in data) {
		if (!data.hasOwnProperty(key)) {continue;}
		var symbol = key;
		var obj = data[key];
		var current = obj[0];
		var prev = obj[1];
		var price = current["4. close"];
		var change = prev["4. close"] - current["4. close"];

		var html = "";
		var priceClass = "greentext", priceIcon="up_green";
		if(change < 0) {
			priceClass = "redtext";
			priceIcon="down_red";
		}

@brendan_c23 no, these, around line 90

	scheduleUpdate: function(delay) {
		var loadTime = this.config.updateInterval;
		if (typeof delay !== "undefined" && delay >= 0) {
			loadTime = delay;
		}

		var that = this;
		setInterval(function() {
			that.getStocks();
			if(that.config.currency.toLowerCase() != "usd"){ // line 90 changed
				that.getExchangeRate();
			}
		}, loadTime);
	},

@sdetweil Ok, I changed the ‘this’ to ‘that’ some lines above! not on those lines, going to try running it after changing the line you just sent

[sdetweil]

@brendan_c23 just the ONE line, line 90…

[brendan_c23]

@sdetweil still waiting to see if it will display, theres a big delay, but no errors have popped up yet

scheduleUpdate: function(delay) {
var loadTime = this.config.updateInterval;
if (typeof delay !== “undefined” && delay >= 0) {
loadTime = delay;
}

	var that = this;
	setInterval(function() {
		that.getStocks();
		if(that.config.currency.toLowerCase() != "usd"){
			that.getExchangeRate();
		}
	}, loadTime);
},

[brendan_c23]

@sdetweil No errors have come up, but it also has not displayed, have been waiting for around 10 minutes

[sdetweil]

open the developers window ctrl-shift-i, console tab, ‘stock’ in the filter field (no quotes)

[brendan_c23]
