Create QR in Appsheet

Good afternoon, I have a problem. I would like to create a QR code, but I am unable to concatenate my data in the URL so that the QR code is created correctly. If someone could help me, I would appreciate it.

I don’t know AppSheet very well, but it seems you are including the literal [Dato1] in the URL. It order to build the URL, I believe you can do something like this:

"" & ENCODEURL([Dato1])
