Question : Multiple Selection buttons passing 2 variables

In a previous post, an expert helped me to make Selection buttons for my record listing. A Button will appear on every line and the user can simply click the button next to the record to make their choice.

http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/PHP/PHP_Databases/Q_26372053.html

I'd now like to add 3 buttons per line:
So instead of 1 button, I'd like to add 2 more buttons on the same line.

I tried to modify this function which worked correctly when passing 1 variable:
<script>
function _submit(teamid) {
document.form.teamid.value=teamid;
}</script>

To this in an attempt to pass a second variable unique to the button being pushed:

<script>
function _submit(teamid,selection) {
document.form.teamid.value=teamid;
document.form.selection.value=selection;
}</script>

Then for each of the buttons, I modified this:
<input type="submit" value="Top10" onclick="_submit(<?=$teamnum?>)";>

To this for the second variable:
Button 1:
<input type="submit" value="Top10" onclick="_submit(<?=$teamnum?>,Top10)";>
Button 2:
<input type="submit" value="Top20" onclick="_submit(<?=$teamnum?>,'Top20)";>
Button 3:
<input type="submit" value="Skip" onclick="_submit(<?=$teamnum?>,'Skip)";>

Ever since I added 2 variables to this functions for multiple buttons, no data is being added to my data and I'm unable to echo the results.

I don't get any Syntax errors though.

Can someone help me correctly process 2 variables in these buttons?

Thanks,

Everything else looks good. Did you try again after fixing the single quotes issue I listed above? I tested like this (and the alert box shows the proper data):

1:
2:
3:

7:
8:
9:
10:
11:
12:
13:
