Sorry if this is uber newbie, but that's me:

I'm trying to insert a javascript pop-up. Here's the code I'm having trouble with:

echo "<td valign=\"center\">";
         echo "<div style='width:100%; height:100%; vertical-align: center;'>";
           echo "<a href=\"javascript:newWindow('sendemail.php?'+document.location.href,'email',400,300,'')">Recommend this page to your friend</a>" style=display: block;>";

             echo "<span>";

It's throwing this error:

Parse error:  syntax error, unexpected T_STRING, expecting ',' or ';' in /home/***/***/tomp.one7media/components/com_marketplace/topmenu.php on line 104

Line 104 being the echo "<a href=\

I appreciate any help!

You forgot to escape some quotes, these two:
)">Recommend this page to your friend</a>
My suggestion is when you're echoing HTML to use single quotes. I found it actually requires less coding in the end.

I'm getting there. I removed "Recommend...." because the output is called from the language file.

Here's the problem:

It's not appearing as a link. Here's the block:

echo "<td valign=\"center\">";
         echo "<div style='width:100%; height:100%; vertical-align: center;'>";

           echo "<a href=\"javascript:newWindow('sendemail.php?'+document.location.href,'email',400,300,'')">" style=display: block;>";

             echo "<span>";
               echo "<img src=\"".$mosConfig_live_site."/components/com_marketplace/images/system/writead.gif\" border=\"0\" align=\"top\" >";
             echo "</span>";
             echo "&nbsp;&nbsp;&nbsp;";

             echo "<span>";
               echo JOO_TELL_FRIEND;
             echo "</span>";

           echo "</a>";
         echo "</div>";
       echo "</td>";

This is what the result is:



It should be a link to pop-up the tell a friend form and I don't know why the "1" is in front of the image.

I'm a total newb and I'm sure it's something stupid.

First off, you need to fix this:
style=display: block;
Add quotes to it.
I'm no expert on javascript, but http://www.pageresource.com/jscript/jwinopen.htm does that help you at all? Also do you have a URL to test this with?

I get this error in Firebug:

unterminated string literal
newWindow('sendemail.php?'+document.location.href,'email',400,300,'') 'style=\di...

Here's a serving of copy pasta for you, just use this code.

PHP Code:

echo '<td valign="center">';
    echo '<div style="width:100%; height:100%; vertical-align: center;">';
        echo '<a href="javascript:window.open(\'sendemail.php?\'+document.location.href,\'email\',400,300,\'\')"> style="display: block;>"';
            echo '<span>';//Why an empty span?
                echo '<img src="'.$mosConfig_live_site.'/components/com_marketplace/images/system/writead.gif" border="0" align="top" >';
            echo '</span>';
            echo '&nbsp;&nbsp;&nbsp;';
            echo '<span>';//Why TWO empty spans?
                echo JOO_TELL_FRIEND; //Is this correct?
            echo '</span>';
        echo '</a>';
    echo '</div>';
echo '</td>'; 


Why do you use the two empty spans, and what is the JOO_TELL_FRIEND thing? Also I'm no expert on javascript but your link would open a new window that if I'm not mistaken would be http://www.example.com/path/to/sendm...th/to/page.php

All you have to do is to scape the " inside the Php code:

)">Recommend this page to your friend</a>"

Must be:

)\">Recommend this page to your friend</a>\"

^ This person has just done my biggest pet hate -.- .. that question has been answerd
