How to show same variable in both body & footer

Hi, a simple question - hoping for a simple answer. Am new to this. Have searched forum, but some answers seem too complex.
In my body, I have a variable, $Amt1 - no problem - it addes up and I can display it in each row.
But, I then want to display it as 'grand total' in the footer - there is no value in it.
How & where do I declare it in order for it to pass from Body to Footer?
Thanks

Hi Izindaba,

Try declaring it as global. In general if you can increment it in the row it ought to be available in the footer.

Thanks - woudld I declare this in header then? Do I use the POST / GET variable fields at all?
Tried using global $Amt1 - but no joy - maybe theres a setting in Chrono Connectivity...?
Thanks for your swift reponses - much appreciated.

Hi izindaba, i have the same problem, have you solved it? Please, let me know.

Redards,
