here you go Tomf, thanks
I want to display the custom form field that contains members Xbox Live Gamertag value under their post info as Gamertag : XXXXvalueXXXX
Then when it is clicked it displays the following code in a small popup.
<iframe src="http://gamercard.xbox.com/insertgamertaghere.card" scrolling="no" frameBorder="0" height="140" width="204"></iframe>
insertgamertaghere.card will need to be XXXXvalueXXXX, the value from the custom form field.
as mentioned, before 3.5.1 i already had the gamertag value displaying in the postbit, not linked though as this is a new feature from Microsoft for Xbox Live gamers.
*EDIT*
i've worked out how to get those custom fields displaying in postbit_legacy again with this code
<if condition="$post[field7]!=''">
<span class="smallfont"><b>Playing:</b> $post[field7]</span>
</if>
<br>
<if condition="$post[field8]!=''">
<span class="smallfont"><b>Gamertag:</b> $post[field8]</span>
</if>
now i just need to link in the Gamertag using the popup VB menu system with that Xbox Live Gamercard URL/Iframe code in it. If someone can help that would be incredible
