Hi Phil, 

i got a problem on calling the method. 

i intended to call a search (SQL method) statement, which exactly like this: 

comment:to select one SQL method 
<dtml-if "_['patient_name']!='' and _['patient_id']==''"> 
<dtml-call "REQUEST.set('b', Search_patient3)"> 

<dtml-elif "_['patient_id']=='' and _['patient_name']==''"> 
<dtml-call "REQUEST.set('b', Selectallpatient)"> 
</dtml-if> 

comment:to use the SQL method which already declared in above 
<dtml-in b>......</dtml-in> 

After the DTML method was called out, it still can return the first page correctly but when i click on the --next XXX records-- it return the error message like this: 
Error Type: KeyError 
Error Value: patient_name 
Traceback:................. 

File C:\Program Files\WebSite\lib\python\DocumentTemplate\DT_Util.py, line 339, in eval 
(Object: _['patient_name']!='' and _['patient_id']=='') 
(Info: _) 
File <string>, line 0, in ? 
File C:\Program Files\WebSite\lib\python\DocumentTemplate\DT_Util.py, line 161, in careful_getitem 
KeyError: (see above) 

Is the above if-else statement gone wrong? it seems failed to pass the parameter to the next page, I tried to display the even and odd record in different color, but also can not work
