I need the old timers to help with a zope dtml-try/dtml-except conditions. I am 
using Zope 2.6.1. My problem is as follows:

<dtml-if expr="fluency_temp<>''">
        fluency - <dtml-var fluency_temp>**

        <dtml-call "REQUEST.set('fluency_test', fluency_temp)">

        <dtml-call "string_to_int(fluency_test ,REQUEST)">

                <dtml-call "REQUEST.set('fluency', y)">

                <dtml-except ValueError> 

                <dtml-call "REQUEST.set('name_error', 'error')">

                <dtml-if expr="name_error=='error'">

                Invalid Number entered 
                <a href="../prek_4_dra_scoring_system/display_student ">
                Click here to go back</a>


                <dtml-call "REQUEST.set('student_full_name', 
                <dtml-call "REQUEST.set('dra', dra_temp)">
                <dtml-call "REQUEST.set('date_scored', ZopeTime())">
                <dtml-call "REQUEST.set('fluency', fluency)">

                <dtml-call expr="update_dra_edl_score_1_4_record_eng(REQUEST)">



I will see an error if I enter a letter and not a number -

Exception Type ValueError 
Exception Value invalid literal for int(): a 

I have trapped for errors like this before using this method but no luck this 

Thanks in advance,

Larry McDonnell
