correct path

@slgora this path in script 1 is not following the agreed folder structure, please replace this

##### CREATE SELECTION DATA SOURCES TABLE #####
source("Functions/Select_data_source.R")

with this

##### CREATE SELECTION DATA SOURCES TABLE #####
source("../../GCCSmetricsII/Code/R_code/Functions/Select_data_source.R")

correct the path for all the function loaded in the script, the paths should be all following this format: source("../../GCCSmetricsII/Code/R_code/Functions/Name__of_the_function.R

also in functions folder add ".R" to the file "Select_data_source" meake sure all the file with function ends with .R
