    a!localVariables(
local!text,
local!checkbox,
local!currentstep: 1,
a!sectionLayout(
contents: {
a!textField(
showWhen: and(local!checkbox="Show field",local!currentstep=1),
label: "Text field",
value: local!text,
saveInto: local!text
),
a!checkboxField(
choiceLabels: {"Show field"},
choiceValues: {"Show field"},
saveInto: local!checkbox,
value: local!checkbox

),

}
)
)

    If you are using a milestone to display multiple steps, you can use the above condition for showWhen. Hope this will help you with your issue.

    the showWhen takes a Boolean. So as long as your logic returns 'true' or 'false' then it doesn't matter what constructs you use.

      As an addendum - I'd strongly encourage you to encapsulate the logic into an Expression rule, separate form the Interface, unless it is only a single value comparison. In this way you can a) independently test it and confirm that it is working as expected and b) you can attach Unit Tests to the rule which means you can provide continual Quality Assurance on the logic as your application evolves. It also makes a clear separation between business logic and presentation which is just good practice.
