Creating an interactive graph but cannot find defined widget referenced

I'm trying to create an interactive graph which uses a dataframe (defined using a second function) which should then be updated with the defined widgets. The code runs fine if I don't make the plot interactive (i.e. I just run my plot function with static values). I've tried combing through some other questions but can't seem to find what I'm looking for (maybe I'm not asking the right qestions).

My original code:

%matplotlib inline
style = {'description_width':'initial'}
TR = widgets.BoundedFloatText(value=1734,min=0,max=10000,step=10,description='Top Reservoir (TVDMSL):',style=style,disabled=False)
BR = widgets.BoundedFloatText(value=1771,min=0,max=10000,step=10,description='Base Reservoir (TVDMSL):',style=style,disabled=False)
NGw = widgets.BoundedFloatText(value=0.88,min=0,max=1,step=0.1,description='NTG (fraction):',style=style,disabled=False)
WD = widgets.BoundedFloatText(value=127,min=0,max=10000,step=10,description='Water depth (m):',style=style,disabled=False)
RR = widgets.BoundedFloatText(value=3500,min=0,max=10000,step=100,description='Reservoir radius (m):',style=style,disabled=False)
D = widgets.BoundedFloatText(value=13.2,min=0,max=10000,step=10,description='Depletion (MPa):',style=style,disabled=False)
nuw = widgets.BoundedFloatText(value=0.29,min=0,max=1,step=0.01,description='Poissons Ratio (bar):',style=style,disabled=False)
Ew = widgets.BoundedFloatText(value=7.9,min=0,max=10000,step=1,description='Youngs Modulus (GPa):',style=style,disabled=False)
def plot(BR,TR,NGw,WD,Ew,nuw,RR,e,intv,D):
# run function without print to get the results dataframe
with HiddenPrints():
df_results = geertsma(BR,TR,NGw,WD,Ew,nuw,RR,e,intv,D)
# defining x-y data for sea bed and reservoir depth
Vd_OB = df_results['Vertical displacement (cm)'].iloc[0]
Vd_UB = df_results['Vertical displacement (cm)'].iloc[-1]
x = [(Vd_UB-1),(Vd_OB+5)]
Seabed_y = (WD,WD)
Res_top_y = (TR,TR)
Res_base_y = (BR, BR)
# formatting plot
f, ax = plt.subplots(figsize=(5,10))
ax.set_ylim([0,e])   # setting y plot limit between 0 and depth of interest
ax.set_xlim(x)   # setting x plot limit
ax.axhline(y=0, color='darkgrey')    # Adding axis through origin
ax.axvline(x=0, color='darkgrey')    # Adding axis through origin
# plotting data
ax.plot(x,Seabed_y,color='steelblue', label='Seabed')    # Plotting seabed level
ax.plot(x,Res_top_y,color='darkorange', label='Top reservoir')    # plotting top res
ax.plot(x,Res_base_y,color='gold', label='Base reservoir')      # plotting base res
ax.plot(df_results['Vertical displacement (cm)'], df_results['Depth'], color='k', label='displacement profile')   # plotting displacement profile
# formatting plot/data
ax.invert_yaxis()
ax.tick_params(top=True, labeltop=True, bottom=False, labelbottom=False)
ax.set_title('Vertical Displacement Profile')
ax.set_xlabel('Vertical displacement (cm)')
ax.set_ylabel('Depth (TVDm)')
ax.xaxis.set_label_position('top')
ax.legend()
interactive_plot = interactive(plot,{'BR':BR,'TR':TR,'NGw':NGw,'WD':WD,'Ew':Ew,'nuw':nuw,'RR':RR,'e':e,'intv':int,'D':D })

I get the following error message:

ValueError                                Traceback (most recent call last)

Just solved this. I was calling interactive plot incorrectly so function was the same but instead of:

interactive_plot = interactive(plot,{'BR':BR,'TR':TR,'NGw':NGw,'WD':WD,'Ew':Ew,'nuw':nuw,'RR':RR,'e':e,'intv':int,'D':D })

I used:

out3 = widgets.interactive_output(plot,{'BR':BR,'TR':TR,'NGw':NGw,'WD':WD,'Ew':Ew,'nuw':nuw,'RR':RR,'e':e,'intv':intv,'D':D })
widgets.VBox([out3])

which worked as I wanted
