newbee question

Hello,

with designer I designed a form that generates this code:

<?xml version="1.0" encoding="iso8859-1"?>

<!--  GNUe-Designer (0.5.5)
       Saved on: 2005-02-12 11:39:32  -->

<form>
   <options/>
   <datasource name="dts_concorsi_master_block" connection="andreas"
               explicitfields="" prequery="Y" primarykey="numero" 
requery="True" table="concorsi"/>
   <logic>
     <block name="master_block" datasource="dts_concorsi_master_block" 
rows="5">
       <field name="fldNumero" field="numero" required="Y" 
typecast="number"/>
       <field name="fldFigura" field="figura" typecast="number"/>
     </block>
   </logic>
   <layout xmlns:Char="GNUe:Layout:Char" Char:height="12" Char:width="47">
     <page name="Page1">
       <label name="lblNumero" Char:height="1" Char:width="7" Char:x="8"
              Char:y="2" text="Numero:"/>
       <entry name="ntryNumero" Char:height="1" Char:width="30" Char:x="16"
              Char:y="2" block="master_block" field="fldNumero" label=""/>
       <label name="lblFigura" Char:height="1" Char:width="7" Char:x="8"
              Char:y="4" text="Figura:"/>
       <entry name="ntryFigura" Char:height="1" Char:width="30" Char:x="16"
              Char:y="4" block="master_block" field="fldFigura" label=""/>
     </page>
   </layout>
</form>

When I try to run it I get a long traceback.
Does gnue-forms.exe sve this traceback to a file ?

The last line is
File "PyPgSql}PgSQL.pyc"  line 3072 , in execute
..... Syntax Error Aat or near "," at character 44

Bye
Andreas
