Just try adding a couple more square brackets for y,

if wells_properties_dropdown=='Rates':
    
    fig_rates=px.line(x=well_data_filtered[well_data_filtered['wells']==wells_dropdown]['date'],y=well_data_filtered[well_data_filtered['wells']==wells_dropdown][['oil bopd','water bwpd','gas mmscfd']],color_discrete_map={'oil bopd':'green','water bwpd':'blue','gas mmscfd':'red'},height=900)
    
    return fig_rates

elif wells_properties_dropdown=='Pressures':
    
    fig_pressures=px.line(x=well_data_filtered[well_data_filtered['wells']==wells_dropdown]['date'],y=well_data_filtered[well_data_filtered['wells']==wells_dropdown][['fthp psi','bhp psi','p* psi']],color_discrete_map={'fthp psi':'green','bhp psi':'blue','p* psi':'red'},height=900)

    return fig_pressures

Thank you so much for your help.
