Pool Management Frameworks

Hi I am trying to get some help with CNtools. Not sure if there is a better place to ask this? It seems to all be fine, I made a wallet, created the pool. The wallet has 60,000 ADA in it. Except when I try to register the pool, it won’t create the certificate. I get this output: – creating registration cert – cardano-cli: Ratio has zero denominator – creating delegation cert – – Sending transaction to chain – – Register Pool and Pledge on Chain – – Protocol Parameters – TN Magic is 42 …

I typed in the percent as 0.04 instead of just 4.
that is a gotcha after building the certs manually.
