I'm trying to get a general aquantence with JS for my basic knowledge, so I've been doing the "my first java script" section of W3chools. In the if/else section though, I tried to copy the "try it editor" exactly to reproduce what they did, but it doesn't seem to work. I wen't over it line by line, so I don't think it's a simple mistake like not adding a "/" or ">"the link to what I'm reffering to is herehttp://www.w3schools.com/myfirst/js06.aspwhat I did is this

<html><body>My first randomized text: <script type="text/javascript">var r=math.random()if (r>0.5){document.write("<a href='http://www.w3schools.com'target='_blank'>learn web development!</a>")}else{document.write("<a href='http://www.refsnesdata.no'target='_blank'>visit refsnes data!</a>")}</script></body></html>

if it makes a difference, I'm using firefox :?I feel like a real newbi (since I guess thats what I am). Please help point me in the right direction

I copied your code and ran it in Firefox and, like for you, it didn't work. However, I opened the Javascript Console ("Tools -> Javascript Console") and it told me "math is not defined".Turns out that you have to use "Math" rather than "math":

var r = Math.random();

so all I have to do is change that one line?I tried it in the "try it editor" and still to no avail...I also used the same code (with the changed line) in a text editor and saved it as an .htm extention, and even that didn't work...I'm sorry if I'm being tedious and asking "stupid" questions

The only other thing I can think of for you is to make sure that what you have in the document.write() calls are on the same line and do not span multiple lines:

// this should work:document.write("<a href='http://www.refsnesdata.no' target='_blank'>visit refsnes data!</a>");// this may break:document.write("<a href='http://www.refsnesdata.no'target='_blank'>visit refsnes data!</a>")
