Re: Is it me?

Hi,

I think the problem is you are confusing the variable names with the
variable contents (which I also did when I first ran the gui).

The first "$" applies to the whole variable. The subsequent "$" (if attached
to the variable name) will be translated and attached to the variable's name
(not contents) and then g4c will look for the whole variable.

So, say "$one$two"
means - look for a variable named "one2"

and say "$one\$two"
means - look for a variable named "one$two"
which when re-translated will result in - look for variable "one2"
