Validating two variables (nested conditionals?)

Yes, of course, you can write such a condition.

This is a completely valid condition to write in the condition field:

if a == 1 and b == 1

I’d like to point out that what @Ivan_jangoux was requesting was not nested conditionals, but compound conditionals (where more than one variable is compared in a single statement, combined with a boolean operator such as AND or OR etc).

As of mid 2024, there is a very genuine need for actual nested conditionals (where the outcome of a first comparison dictates what other comparisons might be made, each of which have their own outcomes). This is sorely lacking from Figma and a huge limitation when implementing any kind of prototype that isn’t basic. Currently, it isn’t possible to add another Conditional as the outcome of the “then” or “else” of a parent Conditional. You can only set a variable, navigate, etc. This is a huge limitation.

Working around such limitations results in overly complex prototypes and buggy statements that are frustrating and difficult to maintain.
