check if a row is empty in a table using shared variable

i'm checking rows of a table,but even if a row is empty the counter "NrOrdreSuivant" doesn't stop.normally if row number 1 is empty i have to get 1 in the counter,but the counter doesn't stop until 18.

the meaning of all that is :in the client VI the counter "NrOrdreSuivant" is always incrementing by 1 in order to get each data in a different row
