asterisk users - Jun 2006 - AW: syntax error

Hi,
> Does anyone know why this row:

${RGPREFIX}]?4:3)
took me some squinting, but the parantheses seem correct - so I presume
the Asterisk parser can't cope with that convoluted an expression (using
a function within a variable, basically).
Try putting LEN(${RGPREFIX}) into a separate variable first, then refer
to it in your GotoIf in a second statement.
