Code works, but need to remove spaces

[djsydeburnz]

I have a small bit of code someone helped me out with do display multiple choices in a profile field on my site. The only problems is that we cannot figure out how to remove the spaces in between the words. For example, it will be dipslay like this:

Straight , Attatched , Looking

insead of:

Straight, Attatched, Looking

Any help is appreciated!!!

</if>
<if condition="$post['field13'] & 2">

	<if condition="$comma=','"></if>
</if>
<if condition="$post['field13'] & 4">
