I am making a console with javascript but I have had problems to discover the origin of the error. I have reviewed the code several times and could not find out what is wrong. Any help is appreciated.

var logStack = 0;
var showTime = false;
var currDate = new Date();
var i = 0;
var tempStr = "temp";

function getLogStr(var lineNum) {
	if(lineNum <= 10 & lineNum > 0) {
		return document.getELementById("line" + lineNum);
	} else {
		tempSTr = "Invalid line!";
		return tempStr;
	}
}

function setLogStr(var newLog, var line) {
	if(line <= 10 & line > 0) {
	document.getELementById("line" + line).innerHTML = newLog;
	} else {
		console.log("Invalid line!");
	}
}

function shiftLog(var line10) {

if(logStack == 10) {
	for(i = 1;i <= 10;i++) {
		setLogStr(i,getLogStr(i + 1));
	}
	setLogStr(10,line10);

} else {
	console.log("There are free lines!");
}
}



function logOnConsole(var newLog) {
currDate = Date();
	if(logStack == 10) {
		shiftLog(new Date().getHours());
	} else {
		setLogStr(newLog, logSTack + 1);
		logStack++;
	}
}

Removes all the var of the arguments of the functions, this is wrong syntax in Javascript.

That is to say: changes function getLogStr(var lineNum) { for function getLogStr(lineNum) {.

These variables as lineNum are declared by the function and are only available within the function (ie: are limited to the scope of the function).

    Thanks, it’s been a while since I programmed in javascript and was more used to Java, so I ended up not touching myself.
