Ok... men hvad skal jeg så gøre ved det tal
Det her er min kilde kode:
<html>
<head>
<title>Trekant</title>
</head>
<body>
<form name="fTrekantBeregn">
<table>
<tr>
<td rowspan="8"></td>
<td>Side a:</td>
<td><input name="inSideA"></td>
</tr>
<tr>
<td>Side b:</td>
<td><input name="inSideB"></td>
</tr>
<tr>
<td>Side c:</td>
<td><input name="inSideC"></td>
</tr>
<tr>
<td>Vinkel A:</td>
<td><input name="inVinkelA"></td>
</tr>
<tr>
<td>Vinkel B:</td>
<td><input name="inVinkelB"></td>
</tr>
<tr>
<td>Vinkel C:</td>
<td><input name="inVinkelC"></td>
</tr>
<tr>
<td>Areal:</td>
<td><input name="inAreal"></td>
</tr>
<tr>
<td>Omkreds:</td>
<td><input name="inOmkreds"></td>
</tr>
</table>
<button name="KnapTrekantBeregn">Beregn</button>
</form>
<script language="javascript">
