variables within a group...

[Goha]

I am trying to declare a variable within a group and is giving me ane error that reads the following: a number, currency amount, boolean or string is expected here

This is how I declare it

in group1 header:
formula @po:
numbervar on := 0;

in details:
@poweron:
if {Viewlog.msg_type} = 213 then
on := on + 1;


Thanks in advance..........

You still have to declare the "on" variable in your detail formula (even if you originally declare and set it in the group header)
