How to write well an expresion?

I don't have an answer as to why the docs are so poor.

It's not as if rdlc lacks users - I'm sure there are plenty of developers using it.

I will try in other way to do it on my form. Then when its save its can put the datas on database.
But why there is no any complete documentation on rdlc (I do looking for on the net all the days)?
Thanx so much Vulpes to do always your best to help.

The documentation for rdlc is pretty awful and I can't find a single example of using an arithmetic operator with a field value :(

I'd see if this is any better:

=Fields!PU.Value * CDbl(2)

Otherwise I'd try writing a custom function:

Public Function MultiplyValue(d As Double, m As Double) As Double

Return m * d

End Function

and then set your expression to:

=Code.MultiplyValue(Fields!PU.Value, 2.0)

data type: number There is not any Null values. For SUM its works. For example: =SUM(Fields!PU.Value) But not for other operaion as I said before...

What is the data type of the PU column and does it have any NULL values?
