Reading your response, Mark, I didn't feel so bad, since the LC Dictionary says for example about mobileControlSet
syntax: mobileControlSet idOrName, PropertyName, value and later explains idOrName - the id or name of the control So I therefore saw the two ways of referring to the control as apparently interchangeable. However, I changed my openCard handler according to your suggestion and nothing at all changed. I think there must be some other factor, but as usual I just can’t see it. Just to labour the point, here is my actual handler with the original names in place. The answer call works as expected: on opencard -- we dynamically create a field for the user to key in the radius global sinputID -- this is all from the LC lesson if environment() = "mobile" then mobileControlCreate "input", "FRadiusText" -- so the user can type in put the result into sinputID answer "opening text field for radius input. ID created is:" && sinputID && "Name is:" && "FRadiusText" mobileControlSet "FRadiusText", "rect", "114,135,163,158" -- this is where the original rect was mobileControlSet "FRadiusText", "visible", "true" mobileControlSet "FRadiusText", "opaque", "true" end if end opencard Still puzzled Graham > On 22 Apr 2020, at 18:34, Mark Waddingham via use-livecode > <use-livecode@lists.runrev.com> wrote: > > On 2020-04-22 17:00, Graham Samuel via use-livecode wrote: >> As usual, the problem will be my fault, but I can’t get a mobile input >> field to appear on a card.
