I have the a knime table like following
| product name : paper clips, price : 2.34 |
| product name : ruler, price : 2.55 |
| product name : calculator, price : 10.23 |
| product name : pencil, price : 4.23 |
| product name : glue, price : 3.13 |
I try to extraction relevant information via a loop, put the extracted information. into variables like following for further processing
For example :
after data extraction,
"product" variable should contains: paper clips, ruler, calculator, pencil, glue
"price" variable should contains: 2.34, 2.55, 10.23, 4.23, 3.13
However the knime loop doesn't work, can anyone advise what's wrong in the loop ? (attached the knime work flow)
