use fieldName into varaiable definition

[employe4_2]

Hi 

I created an application wich load a huge amount of data and use some variable like  : vZone=Subfield(GetFieldSelections( fieldName), ',', 1); 

in order to keep the app fast and responsive i saw i should wright a mximum of calculation in the loading script. 

So i try to replace the variable i created from this window, to the loading script

But in the expression of my variable i use some fields that i load into the loading script. and when i try to define the variable, obviously the field name isn't recognize (because not load yet ?) and put the loading in error.

SO my question is: Is it worth it to create variables into loading script for a better responsive application?

And how do you define variable into the loading script wich use fields not yet loaded?

thanks for the help

Hi Employe4_2,

What do you want to do? You have a large set with data. If I see your expression you want to filter the dataset so it's get smaller before you want to use the dashboard. Is this right?

the expression has nothing to do with my probleme. It's just that i use this expression to create a variable. this expression use a field that i load and i want to create the variable into the loading script using SET or LET i don't remember.

I just discovered tht the function GetFieldSelection() is only a chart function and not a script function... maybe that what's messing around.
