Trying to write an if statement, which calls2 or 3 functions from within it.

code:

{if (($34 != "") && (NR != 1) && ($1 != "F"))
less_than(34, 0, "S1002a")
is_number(34,"S1002a")
}

But this is only treating the first function call, as part of the if.
and always executes is_number. even if the if fails.

Probably a simple error.....?
