Building descriptions Ridge beam not working?

[GuggeGrön]

Hi
I'm in a tight spot timewise and need to use the construction descriptions' dimensioning program

https://www.byggbeskrivningar.se/dimensionering/nockbalkar-och-takasar/

I get an error message even when I don't make any changes to the preset data.
Error message:

Does it work for you??

Seems to be working. Have you tried reloading the page? Tried another browser?

Looks like it's working. Have you tried reloading the page? Tried another browser?

Thanks!

It works when I switch to Microsoft Edge!

Sigh, it only worked when I tested with the preset measurements. When I changed to B1 = 2200 B2 = 2200 and L = 4800, the error message appears.

Sigh, it only worked when I tested with default measurements. When I changed to B1 = 2200 B2 = 2200 and L = 4800, the error message appears.

B1 and b2 cannot both be the same if you have "yes" on opening in gable wall

Thanks for the help!
