Please see [Please read: make it easier to help you](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you/14757). It describes how you format your code.

The likely issue is that you need:

```nohighlight
@variable(myModel, 0<= x[b = 1:length(nBonds)] <= nBonds[b])

```

Here is the relevant documentation: [Variables · JuMP](https://www.juliaopt.org/JuMP.jl/stable/variables/)
