Come on, Corona! Having telephatic abilities is part of the job description, no? ;-))
Being the better psychic i conclude you want to extract the IP-address of your variables content, i.e. the part between "(" and ")".
Carefully reread the part of the man page dealing with "${var%%...}" and "${var##...}" - the one cuts off from the beginning of the variable, the other from the end. You basically do your conversion in two steps, first everything up to "(" then everything behind ")".
I won't spoil the fun finding out how it works, therefore the exact implementation is left as an exercise to the reader.
I hope this helps.
