@Jalibu
Thanks for your reply.
I just can give the url …
https://www.dsbmobile.de
My Problem:
The normal use is to login with user/passwort.
After the login it looks like that:

On this page i have to click on the plan to get the larger version (cutout):

On the right side is a button to get a side for the MM.
See the url …

Another problem: On this site, there is information for 2 days. To switch between the days, i have to klick the “<” or “>” on the upper left hand site.
So the main problem is to get the “https://app.dsbcontrol.de/data/5480ecb0-656c-4da8-be59-e50e376a97aa/eadd132b …” every day and how to pass this changing url every day to the iFrame module. If i use this url, i didn’t have to use a user/passwort.
The second problem is to get the information for the right day … (“<” or “>”)
Any ideas?
