Using vboption inside javascript (template cache)

[Dr.CustUmz]

I am creating a replace via a plugin and however I try to add an option field it is breaking.

$vbulletin->templatecache['footer'] .= '\n'.'<script>var secs=$vboptions[drcsecs],.....

the option exist and has a number in it, yet returns nothing causing my js to error out.
when I manually type a number here though everything is fine.

Why can't I use an option in this case?

further in my code

....value=\"$vbphrase[register](\"+........

I use a phrase and it works just fine...
