Set up an AskFunction:

Activate it and fill in the inputs:

Or deploy it to the cloud:

You can programmatically provide known values:

Now only the second question will be asked:

Provide a first argument to AskFunction to specify how to ask for values:

AskFunction uses the evaluation semantics of the Wolfram Language to skip the questions that are not needed:

Selecting No skips the question about the spouse name:

Use the same syntax as FormFunction and FormObject to specify the appearance of the questions:

Use AskFunction in conjunction with Ask for simple questions or to get the value associated with a key:

AskConfirm can be used to rewind the evaluation to the point before a value was known:

Use AskAppend to accumulate inputs:

Use AskDisplay to display messages:

AskTemplateDisplay takes a function or a template to be applied to the current values:

Use AskedQ to verify if a key has been asked:

AskedValue returns the value without causing a form to be displayed:

When AskFunction is deployed in the cloud, the body is reevaluated at each visit on a clean kernel. Because of this, functions that return random values might return different values at each step:

A possible workaround is using SeedRandom to initialize the pseudorandom number generator with a seed that depends on previous values or on values such as $RequesterAddress:
