Debugger - Trace Watch
In order to check correct functioning of a questionnaire before it is provided for execution, it is recommended to test it using the Trace watch function. Stepping through the whole questionnaire using this functionality allows to trace scripts, which have been executed, questions which have been displayed and answers, which have been provided. This allows to quickly detect potential errors in the questionnaire.
In order to recall the information saved using this functionality, one has to select the Tools > Trace watch item in the top menu.
A window with three tabs will show up:
- The first tab (Answers) shows all answers, which have been provided in response to individual questions.
- The second tab (Trace) shows the scripts called on individual screens. This tab is particularly helpful in script optimization.
- The last tab (Variables) shows variables, which have been defined, along with their assigned values.
