Set layout rule and number

hi All. So I need to set the layout rule like below but the node is giving an error Asked to convert non convertible types. If you have the parameters below it should be correct yes?

Hi @technitutors ,

Check whether your inputs are of the correct type, i.e. a string objecttype for a “string” input.
Also, maybe flattening your Rebar lists helps.

Okay got that going now but now its saying could not load type. The only error that could be coming from is the rebar by curve
