That helps some. If those are your parameters then I'd do something like this:
Place two input fields and two corresponding label fields on the card.
Depending on the state of the pulldown menu, change the text of the label fields and/or hide label field 2 and text field 2. So this way you really only have two input fields to worry about, you're just changing the associated label field so that it looks like you're showing different input fields.
(Untested but...)
Code: Select all
on menuPick pChosen
show lblField2
show txtField2
switch pChosen
case "option 1"
put "what time is it?" into lblField1
break
case "option 2"
put "what is today's date?" into lblField1
break
case "option 3"
hide lblField2
hide txtField2
put "what day of the week is it?" into lblField1
break
end switch
end menuPick
Now you're ready to get the text input from the fields and do what you want with it.
An alternative method might be to have multiple cards with similar-looking controls and switch to a different card depending on the state of the option.
