Hi everyone,
I'm trying to get my head around babel and getting info back into a
table.
The below org file tracks expenses and the perl code simply sums them
up.
The code is working but I now want to get the total back into another table.
What I have is not
working can someone tell me what I'm doing wrong here?
Cheers
Bart
