Hi Beccy,
This sounds like the dependent dropdowns we showcase in Demo 11 in our Form Demos:
http://www.datasprings.com/products...nstrations Typically, you can trigger the question event to display the 2nd combobox by setting a default value on the 1st. However, it sounds like the value from the first dropdown is also dynamic based on a previous page.
You might consider adding a -Please select- at the top which would force them to click on the opton. Something like this:
select '-Please select-' As QuesitonOption, '-1' As QuestionOptionValue
Union All
Select Text As QuestionOption, Value As QuestionOptionValue FROM Lists where listName ='yourListName'
Thanks,
Candace
