javascript two times using the same formule
<p>why cant i use this formule twice?</p>

<pre><code>main.espace = Math.floor(btn.margin + parseInt( ((main.width - main.rowWidth) / main.inRow)/2) );
</code></pre>

<p>in this content:</p>

<pre><code>main.btnC.css({ 'margin-left': main.espace });
main.btnC.css({ 'margin-right': main.espace });
</code></pre>

<p>full script:
<a href="http://jsfiddle.net/ycHVx/" rel="nofollow">http://jsfiddle.net/ycHVx/</a></p>

<p>using the formule once:</p>

<pre><code>main.btnC.css({ 'margin-left': main.espace });
main.btnC.css({ 'margin-right': otherFormule })
</code></pre>

<p>does works but if i use the same formule on the margin-right
doesn't work any more :(
