Hello and thank you for your response.
There are 3 problems in one:
1) It’s still should be [multistep multistep-123 first_step “https://www.capriolandia.it/iscrizione-summer-camp-passo-2/”%5D
OR
[multistep multistep-123 first_step “/iscrizione-summer-camp-passo-2/”]
like you wrote in the answer here: https://www.ads-software.com/support/topic/previous-button-not-displaying.
So, for example, [multistep multistep-123 first_step “www.capriolandia.it/iscrizione-summer-camp-passo-2/”] doesn’t work.
I just remind you that “I’ll be updating the plugin soon so the urls don’t need to be so exact. but until then this is what you can do.” hasn’t done yet. Sorry.
2) Link with get-parameters doesn’t work at all. For example, like this:
[multistep multistep-123 first_step “/iscrizione-summer-camp-passo-2/?parm=1”]
3) Parameters are necessary because form data that passes from the previous step to the next step comes with great delay, after the constructing of the next-step-form. So if you try to constraint the dynamical form, grounding on the data that have been inserted at the previous step you don’t have another option, then to use parameters.
