[TYPO3-english] Extention Tmailform - letter is sent without filling in required fields

[Olga Zhuravleva]

Extention Tmailform - required fields are not required.
In template I've written as in manual, but letter is sent without
filling in required fields:

<tr>	
	<td class="###ADRESS_ERR###">###_LL_LABEL_ADRESS### ###ADRESS_ERR_TXT###</td>
	<td><textarea type="text" ROWS="3" COLS="50"
name="tx_pilmailform_pi1[text][adress]" value="###ADRESS_VAL###"
/></textarea></td>
</tr>
<tr>	
	<td class="###NAME_ERR###">###_LL_LABEL_NAME### ###NAME_ERR_TXT###</td>
	<td><textarea type="text" ROWS="3" COLS="50"
name="tx_pilmailform_pi1[text][name]" value="###NAME_VAL###"
/></textarea></td>
</tr>
<tr>
	<td class="###PERIOD_ERR###">###_LL_LABEL_PERIOD### ###PERIOD_ERR_TXT###</td>
	<td><textarea type="text" ROWS="2" COLS="50"
name="tx_pilmailform_pi1[text][period]" value="###PERIOD_VAL###"
/></textarea></td>
</tr>
Help, please.
