Here is the situation.
One exemple the worst one
Formulas from row 6 to row 302
=CHOISIR(param!L4C2;'Relevé des fonctions'!LC(21);'Relevé des fonctions'!LC(20);'Relevé des fonctions'!LC(108))
At row 144 and 145 the formula change :
=CHOISIR(param!L4C2;'Relevé des fonctions'!L(1)C(21);'Relevé des fonctions'!L(1)C(20);'Relevé des fonctions'!L(1)C(108))
From row 146 to 248, the formula change :
=CHOISIR(param!L4C2;'Relevé des fonctions'!L(2)C(21);'Relevé des fonctions'!L(2)C(20);'Relevé des fonctions'!L(2)C(108))
At row 249 : formula change similar to row 144 and 145.
From row 250 to 289 formula changed similar to row 146 to 248.
Row 281 formula change to :
=CHOISIR(param!L4C2;'Relevé des fonctions'!L(-137)C(21);'Relevé des fonctions'!L(-137)C(20);'Relevé des fonctions'!L(-137)C(108))
From row 282 to 287 formula is similar to row 144 and 145.
At row 288 the formula is :
=CHOISIR(param!L4C2;'Relevé des fonctions'!L(-141)C(21);'Relevé des fonctions'!L(-141)C(20);'Relevé des fonctions'!L(-141)C(108))
From row 289 to 302(end) the formula is ok
During our nomal work with this woorbook, we don’t have any reason to modify that column or the row.
Another type of error: The data that is changing are regular number from 1 to 9. those changes are found out after opening the file.
Hope this will help you
