Getting Information From A Different Table!

[CampinCarl]

I need to get information from a different table to work in my postbit
The info I need is from a table called players, and the fields coming from that table are field 12 and 11
also, this line is meant to check and see if there is a field with the same info as field 5, is it correct? "<if condition="$post['field12'] == $post['field5']">"
If someone could please help me out, that would be great

<if condition="$post['field12'] == $post['field5']">
<if condition="$post['field11']">
		<tr>
			<td bgcolor="#181818" width="20%" nowrap>
				<if condition="$post['field11'] == 0">
					<else />
					<if condition="$post['field11'] < 100"><div class="smallfont">Surf Rank:</div>
					<else />
					<if condition="$post['field11'] < 250"><div class="smallfont">Surf Rank:</div>
					<else />
					<if condition="$post['field11'] < 500"><div class="smallfont">Surf Rank:</div>
					<else />
					<if condition="$post['field11'] < 1000"><div class="smallfont">Surf Rank:</div>
					<else />
					<if condition="$post['field11'] > 1000"><div class="smallfont">Surf Rank:</div>
