Compare list value with operator

Hello everyone, I’m trying to create a script to identify the wall doesn’t meet the requirement such as R-value rating.
I’ve set 3 groups of shared parameters interns for fire-rating, R-value, and Acoustic. Each group has an instance and a type parameter.
I’ve managed to get both instance and type parameter in dynamo in two lists. But when I use “great than” to compare these two lists. the output I have are all null.
I’ve tested this node with two dummy simple lists and the output is true or false, which is what I want.
Really appreciate anyone could help. Thank you

Hi @Macchi

Welcome to Dynamo Forum.

You need to make sure that Object types of X and Y are both the same before you connect to >= node. Use Object.Type node to see there types. If any one of them is string type then use String.ToNumber to convert it to double.

Good Luck!

Thank you Kulkul.

String.ToNumber is the way to go.
