[Koha] How to show description of item type in ISSUESLIP

[Michael Kuhn]

Hi

Our notice ISSUESLIP does contain the following lines:

<<biblio.title>> <<items.barcode>><br />
<<items.itype>><br />
Fällig am: <<issues.date_due>><br />

Unfortunately the content of field "items.itype" is coded, so the output 
of the middle line is just "06" or "20" instead of the actual 
description of the respectve item type (e. g. "CD" instead of 06, or 
"DVD" instead of 20). We have tried to replace "<<items.itype>><br />" by

[% IF items.itype == '06' %] CD<br />
[% ELSIF items.itype == '20' %] DVD<br />
[% ELSE %]
[% END %]

or

[% IF ( items.itype == '06' ) %] CD<br />
[% ELSIF ( items.itype == '20' ) %] DVD<br />
[% ELSE %]
[% END %]

or

[% IF ( items.itype == '06' ) %] CD<br />[% END %]
[% IF ( items.itype == '20' ) %] DVD<br />[% END %]

or

[% SWITCH items.itype %]
[% CASE '06' %] CD<br />
[% CASE '20' %] DVD<br />
[% END %]

or

[% IF items.itype %]
[% USE ItemTypes %]
[% ItemTypes.GetDescription(checkout.item.effective_itemtype) %]<br />
[% END %]

Though, none of these worked - nothing happened. Can anyone please tell 
me the correct way how to achieve this, if this is possible at all?

Best wishes: Michael
