So finally what this macro is doing. In English:
Data values in Ws1 , (first worksheet in "1(sample).xls") column B , are looked for ( attempted to be matched ) to the column A range in Ws2 ( second worksheet in "H2(SAMPLE).xlsx")
If a match is found, then nothing is done. If a match was not found, then the entire row containing the data value in Ws1 is deleted
