How to write a ColdFusion variable an HTML meta tag

I have a share to Facebook button on a page that displays obituaries.

This site is coded in ColdFusion. What I am trying to do is pass the obituarietitle variable to the meta tag og:description like so: 

<meta property="og:description" content="#obituarietitle#">

Through using the https://developers.facebook.com/tools/debug/og/object/ everything is showing up except the description which would be the name of the person who has passed.

The "share" shows #obituarietitle# the variable.I have tried cfoutput tags, cfsets, ect.

I am not seasoned with ColdFusion or og:, I don't know if this is possible.

You must be in a cfoutput region to write variable contents to the output HTML.

So this would work:

<cfoutput>
<meta property="og:description" content="#EncodeForHTMLAttribute(obituarietitle)#">
</cfoutput>

Note the EncodeForHTMLAttribute() - calling this function is necessary to ensure that the value will not break your markup if it contains HTML-specific characters.

It is also a security precaution that prevents HTML injection. Make sure you use this function on all variable values that you output.

Edit: EncodeForHTMLAttribute() is a cousin of the EncodeForHTML() function, member of a group of functions designed to format ColdFusion values in such a way that they are suitable to be used safely in various contexts.
