Custom Postbit Font settings?

[Sweet Cheeks]

I created 3 custom options that each user can set, they are font face, font color and font size. I added the variables to my postbit template

<p><normalfont><FONT COLOR="$post[field16]" FACE="$post[field17] SIZE="$[field18]">$post[message] </normalfont></font></font></font></p>


The problem I am having is that if someone doesnt select a custom size then it is defaulting to a larger font size and overriding my <normalfont> tag :surprised: How can I set a default for these fields to use if the user doesnt set their own, so that I can control the size myself if they dont have their own size set?

Thanks in advance for your help :rambo:
