Browse button and valid URL field disabled in File Reader


I am new to KNIME. I just dragged and dropped the file knime://EXAMPLES/003_Preprocessing/003001_SimpleFlow_with_Statistics onto my LOCAL workspace. On right clicking "file reader" and trying to configure, I find that both the 'valid URL' textbox and Browse button is disabled.

Please help me with this.




This is because the URL is configured via a FlowVariable. You can change the flow variable with the red/blue button right next to the browse button.
