Index Error in the bottle production part! Please help

[89-beep]

Hello everyone,

I'm quite new to bw2 and python as well so I don't understand what is going wrong when running through the parametetrisation of the bottle production part of the notebook.

This is the code:

#The following for-loop is only to guarantee that we can create a new bottle production process

for activity in [act for act in eidb if 'Bottle production' in act['name'] and 'GLO' in act['location']]:
    activity.delete()

#activities and exchanges for simple bottle production model

bottle_production = eidb.new_activity(code = 'test1', name = "Bottle production", unit = "unit")
bottle_production.save()

project_data = [{
    'name': 'M',
    'amount': 0.06,
}, {
    'name': 'D',
    'amount': 200
}]

parameters.new_project_parameters(project_data)

for param in ProjectParameter.select():
    print(param, param.amount)

electricity = [act for act in eidb if act['name']=='electricity production, photovoltaic, 3kWp slanted-roof installation, multi-Si, panel, mounted, label-certified' and 'CH' in act['location']][0]
bottle_production.new_exchange(input=electricity.key,amount=0,unit="kilowatt hour",type='technosphere', formula='20*M/3.6').save()
bottle_production.save()

#mind how the following activity is treated differently! The reason for this will be shown later

polyethylene = [act for act in eidb if act['name']=='market for polyethylene, high density, granulate' and 'GLO' in act['location']][0]
pe = bottle_production.new_exchange(input=polyethylene.key,amount=0,unit="kilogram",type='technosphere', formula='M')
pe.save()
bottle_production.save()

transport = [act for act in eidb if act['name']=='market for transport, freight, lorry 3.5-7.5 metric ton, EURO5' and 'RER' in act['location']][0]
bottle_production.new_exchange(input=transport.key,amount=0,unit="ton kilometer",type='technosphere', formula='D*M/1000').save()
bottle_production.save()

parameters.add_exchanges_to_group("again another group", bottle_production)
ActivityParameter.recalculate_exchanges("again another group")

And this is the error that I get:

Project parameter: M 0.06
Project parameter: D 200.0
