Problem with deploying

[ElmeriVincent]

works locally, what to do

Code where the issue seems to be:

#function for viewing population data when clicked certain button on screen.

def choose():

        #Select what will be shown

        total = "Population Growth Finland"

        female = "Females in Finland"

        male = "Males in Finland"

        selection = st.sidebar.radio("Select what chart will be shown.", [total, female, male])

        data = "data\datapop1.xlsx"

        data = pd.read_excel(data, usecols="A:N")

        #TOTAL POPULATION

        if selection == (total):

                '''**Population growth in Finland 2000-2020**'''

                ### --- LOAD DATAFRAME

                #Visualize population growth

                plost.area_chart(data, "Year", "Population", height=250, color='#0a81c0')

                plost.pie_chart(data, "Year", "Population", height=250)

                data.set_index('Year', inplace=True)

#_____________________________________________________________________________________________________

        #FEMALES OF TOTAL POPULATION!

        elif selection == (female):

                with col2:

                        st.metric("Females of Total Population", "50.69%", "-0.01%, since 2019",)

                "Female population growth"

                plost.area_chart(data, "Year", "Female", height=250, color='#673ba6')

                data.set_index('Year', inplace=True)

        elif selection == (male):

                data.set_index('Year', inplace=True)

        else:
