expression sum and iif help?

Hi All,

SUM(IIF(Fields!NO.Value >= 1, Fields!tsHours.Value,0))

i write this expression inside the group footer row, it give a #error when generating report.

please help

Cheers

Nick

Hi Nick,

The possible reason for this error is that the Sum function can only add fields of the same data type. It is quite possible in this case that the data types of the fields in the TRUE and FALSe part of the If statement is different. Try making the data types same of both the fields by usinf the Conversion functions available.

Hope this helps.

Hi,

I think ure iif() is returning varying datatypes. 0 being a integer and Fields!tsHours.Value returning some other datatype.

Use a conversion function such as CDbl() on both fields.For eg: CDbl(Fields!tsHours.Value) and CDbl(0).This makes either of the values returned as Double.

eg:

Sum(IIf(Fields!NO.value>=1,CDbl(Fields!tsHours.Value),Cdbl(0)))

Thanks Chaubey and Somiya,

You guys are right, after i explicitly convert to same type , then it works.
