How to let user set a variable?

Hi all,

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?

 

Thanks!

Hi,

Combine for example a numeric row filter with appropriate quickform just as in the example in attachment.

Hi Fabien,

thanks so much for the excellent example. Now I understand how the meta nodes and quickform works! :D

Best Regards,
