Selections not working when I publish in browser

[#1]

Hi Friends,

I created a pivot chart and given conditional selections using

=SubStringCount('|' & Concat(distinct Dimensions, '|') & '|', '|Currency|')

In Dimensions List Box I have some other variables like Reporting, Office Etc,

It is working fine on my local machine.

But when I place in browser sometimes its working and some times its not working automatically.

Is there any reason for this?? As it is happening automatically.
