Why can't I use a number slider for the member component of member index?

[o.ismail]

I am trying to use a number slider to select a member from a list using the member index component, but for some reason I keep receiving an error.

in the image I attached I basically want to replace the x value panel that says 10 with an even number slider.

Any help would be great.

Thanks.

Don’t use a panel, use a Series component to generate your set and a slider to chose the member. The panel introduces floating point differences.

For Member Index to work, the formats have to match exactly. The panels are text, and the slider is a number, so it wont be able to find an exact match. You can convert the values to integers. Or use the Find Similar component instead, which can be a bit more flexible. [image]

@o.ismail, please don’t double-post.

thanks for the response, but I realized that I could also connect a number slider to a panel then connect the panel to the member index to fix the issue.

sorry about that, it wasn’t intentional, I thought it would be more appropriate to pose the question as a new topic and I didn’t think to delete the question in the other topic.

I’ll be more careful in the future.
