SSRS is annoying with that.

Use this code to do the division (rename as you wish, this is not Ms Access after all! ).

PUBLIC FUNCTION NDZ(Numerator, Denominator, DZResult)
IF Denominator = 0 THEN
RETURN DZResult
ELSE
RETURN Numerator / Denominator
END IF
END FUNCTION

My problem was to display zero if the value of the denominator is zero, else the division of the two fields.
So what I used is mentioned below,

iff(Field2=0,0,Field1/Field2)

I worked.. Hope it does the same for you all...

shouldn't the operand before Sum(Fileds!field7.Value) be a '+' sign?

All,

I received my answer to this question a long time ago. If you need assistance with a similar problem, please start a new thread as you are more likely to get responses to your question if you post in a thread that doesn't have pages of answers or a thread which says "Problem Solved" in the third or fourth post.

Not a lot of people are going to read beyond my comment of "problem solved."

This is just a friendly public service announcement.

=IIf(
IsNothing(Sum(Fields!divisor.Value)) Or Sum(Fields!divisor.Value) = 0.0,
"",
Sum(Fields!value.Value) / IIf(IsNothing(Sum(Fields!divisor.Value)) Or Sum(Fields!divisor.Value) = 0.0, 1, Sum(Fields!divisor.Value))
)

I just wanted to add a fact:
If you have a division, that does not allow you to use the divisor "1" instead of "Nothing" you can still use the suggested solutions in this tread:

What you have to do is use your conditions twice: first your "old" way: IIf(Sum(Fields!divisor.Value) = 0.0, "", ...
Then in the dvision: ...Value) / IIf(IsNothing(Sum(Fields!divisor.Value)) Or Sum(Fields!divisor.Value) = 0.0, 1, Sum(...

As you can see, you still have a divsion by 1 implemented but it can never be reached as you ruled it out before.
That makes the renderer and you happy ;)

I tried this approach. it ddn't work for me. please help me..

Public Function Divider (ByVal Dividend As Double, ByVal Divisor As Double)
If IsNothing(Divisor) Or Divisor = 0
Return 0
Else
Return Dividend/Divisor
End If
End Function

=Code.Divider(cstr(cint(Sum(Fields!DRGMatch.Value),CountDistinct(Fields!LocalID.Value+Fields!UIUserID.Value)*100)))+"%"

got the below Error:

Textbox16.Paragraphs[0].TextRuns[0]’ contains an error: [BC30198] ')' expected._

My guess is that you have a paren in the wrong place. Check the bolded text and play around with where the parens should be.
