XSLT

I Know this is a really shitty (excuse my french) post, so please bear with me and I will try to do as you tell me to make it easier for me to benefit from your help. My problem is that I'm only recieving an Error parsing xslt error. I will post my code and then explain a bit further.

My code looks like this. God bless you, if you read through it all.

My querystring I'm using is: ?solution=1062&playlist=1063&startdate=2009-07-22T00:00&enddate=2009-07-22T23:59

If i change the querystring to ?solution=1062&playlist=1063?&startdate=2009-07-22T00:00&enddate=2009-07-22T23:59

the output ht-/xml is

 2009-07-22T00:002009-07-22T23:5910621063?<slots><slot id="slot1" starttime="2009-07-22T00:00" endtime="2009-07-22T23:59" /></slots>

Also if I comment out (in good old html  style) the first call to the recursive template namely this:

<slots>

<slot id="slot1"
starttime="{umbraco.library:RequestQueryString('startdate')}"
endtime="{umbraco.library:RequestQueryString('enddate')}">

<!--
<xsl:apply-templates
select="$currentPage/ancestor::root/descendant::node[@id=$solution]/node[@id=$playlist]/node[not(umbraco.library:DateGreaterThan($startdate,./data[@alias='StartDate'])
or umbraco.library:DateGreaterThan(./data[@alias='EndDate'],$enddate)
or (umbraco.library:ShortTime($startdate) >
./data[@alias='StartTime']) or (./data[@alias='EndTime'] >
umbraco.library:ShortTime($enddate)))][1]" mode="playlistItems">

<xsl:with-param name="playlistDate" select="$startdate" />

<xsl:with-param name="listedids" select="0" />

</xsl:apply-templates>
-->

</slot>
</slots>

My output looks like this:

 2009-07-22T00:002009-07-22T23:59106210632009-07-16T20:56:20<slots><slot id="slot1" starttime="2009-07-22T00:00" endtime="2009-07-22T23:59" /></slots>

Your help is much appreciated, feel free to school me in other coding matters than my essential problem here, I can only get better from where I am now.
