Can't specify the number of rows in Row sampling tool with flow variable

KNIME Analytics Platform

I’m using the Row Sampling tool. I want to specify a fixed number for sampled rows, and take the value from a flow variable. In the flow variable configuration setting tab, the fields “fraction” and “count” are not selectable. Does thi s mean it is not possible to specify the number?

Hi there!

I would say you do not have a flow variable with types double (for fraction) and integer (for counts) :wink:

Thanks so much, that was indeed the problem! The flow variable was of string type, converted it now all works.
