Processes can contain three kinds of Node:
Interactions (Questions and simple information displays)
Actions (things which happen without the user being aware - for example: variable updates, database actions)
Sections (Groupings of Nodes, which can include other Sections)
So if you want to add a question, then select the Interactions sub-menu and choose exactly the kind of Interaction you want to add.
To be more precise, within a Process, under the Nodes tab, click +Add button, choose the Interactions menu, then perhaps the Common Question Types sub-menu, as shown below
For example, let us add a question which requires input of some text from the user i.e. select to add a "Text Input" question.
In the dialogue which then appears, the large input box is where you enter the text of the question.
For those familiar with HTML, the text of questions/displays can make use of markup tags.
The input box below labelled "Name for value entered" permits you to define a symbolic name for the (text) value which the user will enter in response to the question.
This enables us refer to, and use, this value elsewhere.
When you add the question, it will immediately be flagged with a System Issue, because Logiak is vigilant on your behalf.
If you enter a symbolic name for a text value, how can you quote the value in later questions?
