Z Error Bars in 3D scatter plot

I have 3 columns of data: x, y, z, and length of z error bars. Is there any way of plotting my points with z error bars? It seems easy enough to do, but they just don’t show up…
Thanks a bunch!

Are you using the web app or an API?

What have you tried before?

I’m using the web app. I’ve tried clicking the traces tab, then going to error bars, z error bars, and for value I select data. %, +/-, and square root show up, but when I select any data the bars vanish. Is there a special way to import a column of data that you want to use as error bars?
