expression issue

[chematos]

Hi,

I need help with this expression:

sum({$<NumPeriodo={'<=$(NumPeriodo)'},%KeyPeriodo={"=%KeyPeriodo"}>}Promedio)

I thought that this would work but is wrong. First of all, I have this fields:

NumPeriodo: Period`s number, being 01 for August and 11 for July.

PERIODO: Is compossed by Year+NumPeriodo, for example August 2010 would be 201001

%KeyPeriodo: This is an ID to identify the periods so 1 identify the periods of 2010(August2010 to July2011), 2 = (Aug2011 - July2012) , etc.

When the user selects a PERIODO, for example 201107 (Year 2011, NumPeriodo 07) I need to add all the values of Promedio since NumPeriodo=01 to NumPeriodo = 07. The %KeyPeriodo would be 2 for all that periods.

Help me, please.

Thank's,

Chema

I'm a little desperate. Why if I create a textObject and I write =NumPeriodo, I get 07 which type is a Number and when I write the next expressions the result is different??

sum({$<NumPeriodo={"<=07"}>}Promedio)  ----> Working fine!

sum({$<NumPeriodo={"<=NumPeriodo"}>}Promedio)  ----> Working wrong!

Could someone explain to me?Any clue?

Unless I'm missing somthing:

NumPeriodo={"<=NumPeriodo"}   asking if NumPeriodo is less than or equal to itself.

Hi,

I tried with sum({$<NumPeriodo={"<=NumPeriodo)"}>}Promedio) but it didn't work.

This expresion is working finally!!

sum({$<NumPeriodo={'<=$(=NumPeriodo)'}>}Promedio)
