unable to run python code on a combined table to export the table to a csv

[Pandadev]

I have created a table which is built by apending multiple tables. But when I try to add a python script to apend this table to a csv everytime there is a refresh , I get an error 

Formula.Firewall: Query 'Summary' (step 'Added Conditional Column') references other queries or steps, so it may not directly access a data source. Please rebuild this data combination.

in the advanced editor here is what my code looks like , cant work out what I am doing wrong

let
Source = Table.Combine({#"Futures_0-2_days", #"Futures_0-5_days", #"Futures_6-14_days", #"Futures_15-31_days", #"Futures 30 days preceeded by N3", #"Futures 30 days preceeded by O3"}),
#"Run Python script" = Python.Execute("d = pandas.DataFrame(dataset)#(lf) #(lf)d.to_csv('C:\QC Checker\QC Checker Metrics.csv, index=False)#(lf)",[dataset=Source]),
in
#"Run Python script"

Hi, @Pandadev 

The tables in power query can be recongnized as pandas object directly, so you can simply call other tables by calling relevant pandas object. I'd like to suggest you refer to the following link to see if it helps

@Pandadev , this statement should have one more single quote

.to_csv('C:\QC Checker\QC Checker Metrics.csv, index=False)

like

.to_csv('C:\QC Checker\QC Checker Metrics.csv', index=False)

I still get this error Formula.Firewall: Query 'Futures Summary' (step 'Run Python script') references other queries or steps, so it may not directly access a data source. Please rebuild this data combination.
