Hey Lisa,

I made the replacement and have some questions:

- Should the name of the new component have to be the same as the one you are replacing (it doesn’t appear to make a difference neither throws errors)?

eg:

*replace_comp!(m_fund, impactsealevelrise, :impactsealevelrise, reconnect = true )*

vs.

*replace_comp!(m_fund, impactslrparameter, :impactsealevelrise, reconnect = true )*

- I get an error when I try to evaluate the model using the new component. Thoughts or suggestions would be much appreciated. The full stacktrace is below:

MethodError: no method matching getindex(::Float64, ::Mimi.FixedTimestep{1950,1,3000}, ::Int64)

Closest candidates are:

getindex(::Number, !Matched::Integer…) at number.jl:82

getindex(::Number) at number.jl:75

getindex(::Number, !Matched::Integer) at number.jl:77

…

Stacktrace:
