morning and sorry for my english.
i need to count() the occurrence of a repeated section only if the <data> field is equal to a preselected month.
i'm arrived up to here: substring(data; 6; 2) = campo2
data field contains something like 2010-11-12 and campo2 is a combo box that contains a nuber from 1 to 12.
do i need to use val function ?
how ?
any suggestion ?
tvm, milko.
