The application 's construction is correct but All screen (Web) are opening in the same time and I did configure it to open each window after clickin on the right button .I don’t understand what’s wrong .The activity starter open the wrong URL , all it reverses .

Thank you for your help !

Best regards ,


OK, some nice screenshots…now show us your blocks, html, designer etc. so we can see what you are trying to achieve…

Hi TIM !

Ok, all HTLM and URL are correct and correctly positioned , nothing to do with URL and HTLM. I did exactly the same app , it does work .

Best regards,


first set the parameter for the activity starter, then start the activity
PS: next time you might want to provide a readable screenshot of your relevant blocks only…

Hi ,

So what shall I do ? rebuild all over to make it works .
1-first step add an activity starter
2-then organize the blocks of the activity .

Am I right ?

Thank you for your help .

Best wishes ,



Tai ,

Ok Tai ,wonderful, you understood the problem.

It’s done = it open up the right url .

But still all the windows or boxes open in the same time why ?


my correct name is Taifun. Thank you.

unfortunately I do not understand, you might want to elaborate what exactly is happening and what you expect to happen instead
also an updated readable screenshot of your relevant blocks might help

To get an image of your blocks, right click in the Blocks Editor and select "Download Blocks as Image". You might want to use an image editor to crop etc. if required. Then post it here in the community.
