I am very a beginner in Knime. How can I let the user set a variable?
For example: "threshold"
I habe a table with two columns: student, score.
I want to select all the students whose score > "threshold", so the threshold will be setted by the user. Which node should I use?
I know, right click the workflow and select the "workflow variables..." can set a globle variable. But are there other methods?
