Brian,

There are a few different problems here, some on our end, some on yours. More 
below.

> Hello. I was wondering if there were some changes to how IDV scripting works

The display has not been moved to a new location. I believe the problem is 
there is no bundle associated with this ISL script. Create the SkewT bundle you 
are interested in and reference it with the "bundle" tag (see attached).

I believe it is incorrect to have HTML character entities here. Try:

<if>
    <![CDATA[${HH} > 00 and ${HH} < 13]]>
    <then>

instead of

<if expr="${HH}&gt;00 and ${HH}&lt;13">

See

When putting an example ISL script together for you (see attached), we 
discovered a problem where the current IDV will not be able to properly run the 
ISL script. Please check the nightly build tomorrow for the bug fix.
