Hello! I dynamically create more form fields by calling a dtml method and then returning (refreshing the formular document which displays more fields) By doing it the previously introduced values of the fields disappear, cause I create a new form page Is there a possibility (may be a HTTP feature) to restore the values not declaring and saving each value in a separate variable? Thank you in advance Andrei

I am assuming your formular page looks like, and that init_field_count and field_count_incr are properties available to the DTML method. Then something like this will work <form method=post action=.> <dtml-if "not _.has_key(field_count)"> <dtml-call "REQUEST.set('field_count', init_field_count)"> <dtml-else> <dtml-call "REQUEST.set('field_count', field_count + field_count_incr)"> </dtml-if> <input type=hidden name=field_count value=<dtml-var field_count> <dtml-if "field_count == init_field_count"> <dtml-in "range(field_count)"> <input name=<dtml-var "'var'+_['index-sequence'])"> ...> </dtml-in> <dtml-else> <dtml-in "range(field_count-field_count_incr)"> <input name=<dtml-var "'var'+_['index-sequence']"> value="<dtml-var _['var'+_['index-sequence']]>" ...> </dtml-in> <dtml-in "range(field_count_incr)"> <input name=<dtml-var "'var'+_.str(_.int(_['index-sequence'])+field_count)"> ...> </dtml-in> </dtml-if> <input type=submit name=command value="Add More Fields"> <input type=submit name=command value="Save" </form> This is tending twoards abuse of DTML and may be better suited for a (Script) Python

If I do understand correctly, you have a form, where the user can input some values. Then on submit you process the values and return a new form with other input elements I assume. To transport your values from page to page, you can use hidden form elements or use one of the session-products. The first method is more convenient for the user if there are not too many elements.
