Concatenation issue in PHP

[vishalonne]

I was trying to display name and address phone no in mail and I perfectly done it using the following piece of code -

</tr>
<tr>
<td align="left"><p>'.$admin_message['message'].'</P></td>
</tr>
<tr>
<td align="left"><p>Kind Regards</P></td>
</tr>
<tr>
<td align="left"><p>'.ucwords($finance_info['fi_schoolname']).
'<br />'.ucwords($finance_info['fi_address']).
' <br /> Email :- '.ucwords($finance_info['fi_email']).
'<br /> Contact:- '.ucwords($finance_info['fi_phoneno']).'</P>
</td>
</tr>

But when I am trying to add Logo in line No 9 of above code snippet for change refer the line number 19 if($_SESSION['eschools' in below code DreamWeaver shows error in concatenation -

$message='<table width="80%" cellspacing="2" cellpadding="2" border="0">
<tr>
<td align="left"> Dear '.stripslashes(ucwords($eq_wardname)).',</td>
</tr>
<tr>
<td align="left"><p>Thank you for contacting '.ucwords($finance_info['fi_schoolname']).' Admissions Unit. If you need to speak to us regarding your admission please walkin to our Admissions Unit or Contact us by using your referral Enquiry ID : ES'.$insert_id.'</P>
</td>
</tr>
<tr>
<td align="left"><p>'.$admin_message['message'].'</P></td>
</tr>
<tr>
<td align="left"><p>Kind Regards</P></td>
</tr>
<tr>
<td align="left"><p>'.
**if($_SESSION['eschools']['schoollogo']!=""){ echo displayimage("images/school_logo/".$_SESSION['eschools']['schoollogo'], "140"); }
.'&nbsp;&nbsp;&nbsp;&nbsp;'.**
ucwords($finance_info['fi_schoolname']).'<br>'.ucwords($finance_info['fi_address']).' <br />
Email :- '.ucwords($finance_info['fi_email']).'<br>
Contact:- '.ucwords($finance_info['fi_phoneno']).'</P></td>               
</tr>    
</table>';

//use assignment operator http://www.php.net/manual/en/language.operators.string.php

$message = 'start of output string';
if (true)
{
    $message .= 'conditional body of string';
}
$message .= 'end with whole string since it's begun';
