I’m using UiPath APPs and I need to disable one button based on the content of one field.

Please look at the picture attached to understand the error.

The image shows a programming interface with an error message indicating that "A variable must be specified" when trying to set the value for "ButtonPage.Button.Disabled" inside an "If/else" condition. (Captioned by AI)
