Less than...

PHP Code:

<if conditional="$auinfo[total] < $auinfo[posts]">
Less than stuff here
<else />
Greater than stuff here
</if> 


... should work. As far as your parsing errors it's most likely due to you not encapsulating the variables. For example,

PHP Code:

<if condition="$auinfo[field7] == I do not have a package"> 


should be...

PHP Code:

<if condition="$auinfo[field7] == 'I do not have a package'"> 


Note the single quotes around the value.
