numFIles is an Integer. I've made a workaround on this by generating a random 0-1 million, creating a fraction, and then multiplying by my original value. Just a workout, but works in my case.

On second thought "bug" might be a bit harsh, as no function in JMeter will currently transform those values by itself (yet?). To answer your question, you could use __evalVar function to convert your Integer into a String: ${__Random(0,${__evalVar(numFiles)})} Regards, Feli --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@jmeter.apache.org For additional commands, e-mail: user-h...@jmeter.apache.org This email, including attachments, may contain information that is privileged, confidential or is exempt from disclosure under applicable law (including, but not limited to, protected health information).
