UFT Tool runs more than one iteration always

[cthossain]

Even after deleting all data/values from EACH OF THE CELL from Global data sheet by Edit>Clear>All , my test script wud run thrice ( for Three previous global data sheet parameterized values ) . I had no clue as to why it is run thrice while the data sheet is empty. Then I Found that even the data sheet was empty, three block selection was shown in three rows ( but there was no value). Then I manually selected ALL THE ROWS (mouse click and drag), and then Edite>Clear>All , only then I was able to delete the values from the global data sheet and script runs once.  My question is how come the scipt runs for more than once when there is no data sheet rows/values.
