How to get the values of a multi combo box to a next page?

[simonbahlmann2]

Hey Guys! First of all I am sorry for my bad english.

Overview:

• I created a list of Presents with multiple propertys as an app variable.
  

  

• Now I created a selection page.
  

  

• And to show all the prensents I created a output page.
  

Intention:

1. select for example hobby1 and hobby2 in the multi combo box
2. press the button to open the output page
3. show all the presents with the property hobby = hobby1 or hobby = hobby2

Maybe somebody can help me? Thank you!

Output page

Add page parameter hobbys type text.

Set repeat with of card to formula.
SELECT_BY_REGEX(appVars.presents, "hobbys", params.hobbys)

Bind card title and content to repeated item.

Combo box page

Add page variable selected (list of objects with token text property).

Attach Set page variable and Open page to button tap.

Set page variable selected to selected tokens of combo box.

Set Open page to output page, set hobbys parameter to formula.
JOIN(PLUCK(pageVars.selected, "token"), "|")

Set combo box list of options to formula.
GROUP(PLUCK(appVars.presents, "hobbys"),item,{token: key})

Hey @dwidge I have followed your instruction and it works well.

But now there is an little new problem, because I want to get all results if there is no option selected.
At the moment I get no result if I do not select an option.

Thank you for your time!!!
