Document Classes ⇒ Latex document class issue

[mn_hossen]

Hi,
I'm preparing my manuscript in Applied Intelligence (Springer Nature) overleaf template. As the journal mentioned reference format should be numbered and in journal instruction they mnetioned to use \documentclass[pdflatex,sn-basic]{sn-jnl}. But that \documentclass{} is authoryear format. When I use \documentclass[numbers]{natbib} for generating number format, it shows below error:

See the LaTeX manual or LaTeX Companion for explanation.
Type H <return> for immediate help.
...

l.42

The package natbib has already been loaded with options:
[authoryear]
There has now been an attempt to load it with options
[numbers]
Adding the global options:
authoryear,numbers
to your \documentclass declaration may fix this.
Try typing <return> to proceed.

After that, when I try global options like: \documentclass[pdflatex,sn-basic,numbers]{sn-jnl}
\usepackage{natbib}

Still it is not number format and the error persists.

Thanks in advance.

You could try

Code: Select all

\PassOptionsToPackage{numbers}{natbib}

before your \documentclass line.
If that doesn't help, please provide a minimal working example that demonstrates your problem and a link to the class file you're using.

@Rainer
It doesn't work.

I attached the overleaf link:

Thanks

Well, if you wish to discuss your problem here, you should present it here. A link to join your project won't do, IMHO.
