[SOLVED] vbulletin doesn't like ternary operators?

[Dr.CustUmz]

for simplistic code sake I'm trying to use ternary operators in my products.

Here's what im trying to simplify:

if ($vbulletin->options['drc_embed_vine_smpl']) {
    $drc_embed_vine =  '<iframe src="https://vine.co/v/$2/embed/simple" width="480" height="480" frameborder="0"></iframe>';
  } else {
    $drc_embed_vine =  '<iframe src="https://vine.co/v/$2/embed/postcard" width="480" height="480" frameborder="0"></iframe>';
  }

Now I have tried

$drc_embed_vine = '<iframe src="https://vine.co/v/$2/embed/'.(($vbulletin->options['drc_embed_vine_smpl']) ? "simple" : "postcard").'" width="480" height="480" frameborder="0"></iframe>';

$drc_embed_vine='<iframe src="https://vine.co/v/$2/embed/'.(($vbulletin->options['drc_embed_vine_smpl'])?'simple':'postcard')).' width="480" height="480" frameborder="0">';

$drc_embed_vine='<iframe src="https://vine.co/v/$2/embed/'.(($vbulletin->options[\'drc_embed_vine_smpl\'])?'simple':'postcard')).' width="480" height="480" frameborder="0">';

not one of these worked =/

although

$drc_embed_vine = '<iframe src="https://vine.co/v/$2/embed/'.(($vbulletin->options['drc_embed_vine_smpl']) ? "simple" : "postcard").'" width="480" height="480" frameborder="0"></iframe>';

does use the postcard option but it does whether the option is yes or no

btw

$vbulletin->options['drc_embed_vine_smpl']

is a simple yesno boolean

where am i going wrong =/
