reCAPTCHA keep saying incorrect-captcha-sol - recaptcha

Question

I have this form
<form action="" method="post" enctype="multipart/form-data" name="form1" id="form1">
<tr>
<td width="32%" valign="top"> <strong class="main_title">Select Category: </strong></td>
<td width="68%" valign="top" class=""><? $qu="SELECT `id`,`name` FROM `linkvideos_category` WHERE `status` = '1'"; $rs=$Q($qu); ?>
<select name="category" class="blacktext" >
<option>Choose Category</option>
<? while($dis=$F($rs)) { ?>
<option value="<?=$dis['id']?>"> <?=$dis['name'];?></option>
<? } ?>
</select></td>
</tr>
<tr>
<td colspan="2" valign="top" class=""> </td>
</tr>
<tr>
<td valign="top"> <strong class="main_title">Upload Image: </strong></td>
<td valign="top" class=""><input type="file" name="imagefile" /> </td>
</tr>
<tr>
<td colspan="2" valign="top" class=""> </td>
</tr>
<tr>
<td valign="top"> <strong class="main_title"> Your Link : </strong></td>
<td valign="top" class=""><input name="link" type="text" size="50" /></td>
</tr>
<tr>
<td colspan="2" valign="top" class=""> </td>
</tr>
<tr>
<td valign="top"> <strong class="main_title"> Link Title : </strong></td>
<td valign="top" class=""><input name="linkname" type="text" size="50" /></td>
</tr>
<tr>
<td colspan="2" valign="top" class=""> </td>
</tr>
<tr>
<td valign="top"> <strong class="main_title">Description:</strong></td>
<td valign="top"><label>
<textarea name="desc" cols="40" rows="10"></textarea>
</label></td>
</tr>
<tr>
<td valign="top"> <strong class="main_title">Security Code:</strong></td>
<td valign="top">
<? if ($error==3) { ?>
<font color="red">Invalid Code Entered</font>
<?}?>
<?php
require_once('captcha/recaptchalib.php');
echo recaptcha_get_html($public_key);
?></td>
</tr>
<tr>
<td colspan="2" valign="top" class=""> </td>
</tr>
<tr>
<td colspan="2" valign="top" class=""> </td>
</tr>
<tr>
<td colspan="2" align="center" valign="top" class=""><input type="submit" name="Submit" value="Submit" class="btns" onclick="javascript:return check();" /></td>
</tr>
</form>
and i'm verifying the captcha with this
$resp = recaptcha_check_answer ($private_key,
$_SERVER["REMOTE_ADDR"],
$_POST["recaptcha_challenge_field"],
$_POST["recaptcha_response_field"]);
if (!$resp->is_valid) {
$error = 3;
echo"<script>window.location='submit_linkvideo.php?error=3';</script>";
}
and every time it's telling me the captchas invalid and saying incorrect-captcha-sol, am I missing something? I've tested it and the recaptcha values arn't being submitted.

Answer 1

Fixed it by ending a table before the form then starting the table again once inside the form.
