linking to admin addon module

[monstertocode]

hi everyone, i have been having trouble with the links of my addon module.

I have a function in my module that is only allowed for the admin and it's called "insert" and the module is called client_document.

What i want to do is a insert into the database with this action and this is what i have

<form method="post" action="index.php?module=client_document&action=insert" enctype="multipart/form-data">
	<input type="hidden" name="userid" value="{$data["userid"]}" />
	<table class="clientssummarystats" cellspacing="0" cellpadding="2">
		<tr><td width="40">{$_ADDONLANG[clientsummary][filetitle]}</td><td class="fieldarea"><input type="text" name="title" style="width:90%" /></td></tr>
		<tr><td>{$_ADDONLANG[clientsummary][filename]}</td><td class="fieldarea"><input type="file" name="uploadfile" style="width:90%" /></td></tr>
		<tr>
			<td width="40">
				{$_ADDONLANG['clientsummary']['type']}
			</td>
			<td class="fieldarea">
				<select type="text" name="typeid" style="width:90%">
					<option disabled selected>{$_ADDONLANG['clientsummary']['option']['default']}</option>
					{foreach ($filetypes as $type)}
						<option value="{$type->id}">{$type->typename}</option>
					{/foreach}
				</select>
			</td>
		</tr>
		<tr>
			<td>
			</td>
			<td class="fieldarea"><input type="checkbox" name="adminonly" value="1" />
				{$_ADDONLANG[clientsummary][fileadminonly]} 
				<input type="submit" value="{$_ADDONLANG['global'][submit]}" />
			</td>
		</tr>
	</table>
</form>

and went i try it to insert a file well it doesn't and send me to the admin dashboard.

just for additional information in the insert function the only thing that exists there is a dd().

Thanks.
