Error with ExcelRpt_SetCellRangeAttribute for ER_CR_ATTR_FORMULA

Hi

Using CVI 8.5

My application needs to write an excel file.

some test code :

            __caErrChk (ExcelRpt_SetCellValue(SheetMoteur, "A1", CAVT_INT, 30));
            __caErrChk (ExcelRpt_SetCellRangeAttribute(SheetMoteur, "A2", ER_CR_ATTR_FORMULA, "=SI(A1=30;0;1)"));

The first line is OK, and 30 is written in A1.

The second line always fails.

'SI' if the french version of 'IF'

if I write directly the formula "=SI(A1=30;0;1)" under excel in A2, it works fine...

            __caErrChk (ExcelRpt_SetCellRangeAttribute(SheetMoteur, "A2", ER_CR_ATTR_FORMULA, "=A1"));

the formula "=A1" works fine.

Thanks
