We sometimes receive support questions like this: I cant go to the next step when filling form, what is the problem?
Some fields in earch form are required. The next or save button is disabled as long as you haven't filled in each required field.
Some fields have validation like the budget field needs a number, not text. If you don't want to provide a budget, leave the field empty, it is not required.
If you still experience issues, fill in the form, make a screenshot and send it to firstname.lastname@example.org, so we can see what you see.
