How to get Level "Elevation" value to put into other Family Parameter

[Harywijaya.2]

Hi All,

I am so noob in the Dynamo and tried to learn it.
I struggling to get the Level elevation that I will use for my family parameter.
I got the error message as shown below and already 2 days can’t found the solution (I already read some post in this forum)

Thank you everyone, Bless you

Hello…Dont know what kind your parameter is, but it isnt a number, try insert string from object or try this one her from Springs…where we have the options to control digits…
