User inputted Iframe adding '\"

So I know what the problem is I just can’t find the solution.

I have a text field that I need a user to input their bandcamp embed iframe and then display on a page.

I have it almost there but in firebug I can see that in the code for the iframe it looks like it’s escaping. I’ve tried a few things but always get something like this in firebug:
<iframe seamless="" src="\"http://bandcamp.com/EmbeddedPlayer.....

This is my text field:
<input id="bandcamp-id" type="text" name="bandcamp-id" value="<?php echo custom_field('bandcamp-id'); ?>" />

and here’s the rest:

function group_header_fields_save( $group_id ) {
global $bp, $wpdb;
$plain_fields = array(
'genre',
'bandcamp-id'
);
foreach( $plain_fields as $field ) {
$key = $field;
if ( isset( $_POST[$key] ) ) {
$value = $_POST[$key];
groups_update_groupmeta( $group_id, $field, $value );
}
}
}
add_filter( 'groups_custom_group_fields_editable', 'group_header_fields_markup' );
add_action( 'groups_group_details_edited', 'group_header_fields_save' );
add_action( 'groups_created_group',  'group_header_fields_save' );

// Show the custom field in the group header
function show_field_in_header( ) {
echo "<p> <strong>Musical Genre: </strong>" . custom_field('genre') . "</p>";

echo "<p>" . custom_field('bandcamp-id') . "</p>";
echo do_shortcode('[gallery]');
}
add_action('bp_group_header_meta' , 'show_field_in_header') ;
}
add_action( 'bp_include', 'bp_group_meta_init' );
