Regular expression question

Hi all,
Does anyone see any problems with the following
regular _expression?
[(\$\\d{3}\$[-]?\\d{3}[-]?\\d{4})?][(\\d{3}[-]?\\d{3}[-]?\\d{4})?]
The first [] is supposed to detect (123)456-7890 and
the second [] is supposed to detect 123-456-7890 where
also 1234567890 is valid.
It is also a bit forgiving, if you mistype it as:
123-4567890, it would take it.
First [] and second [] work fine separatley, but as
soon as I put them together to create an OR, I get a
parse exception.
Any clues as to why?
Thanks
Payam.

Try this (I made the assumption that the phone number should be the only thing in the string):
^\$?\\d{3}\$?-?\\d{3}-?\\d{4}$
This will match for a ten digit sequence with or without parenthesis around the area code, and with or without dashes after the area code and exchange.

See also this thread for some other patterns with slightly different behavior. As for what's wrong with your attempt here...
First [] and second [] work fine separatley, but as soon as I put them together to create an OR, I get a parse exception.
How exactly do you "put them together to create an OR"? Do you include all the [ and ] characters as shown? (This would be interpreted as a character class, which probably is not what you want here.) Do you just put the two expressions next to each other, as show (which represents a sequence, not an OR) or do you include a | to represent an OR?

Jason,
Thanks for your reply. It works fine.
Jim,
I was trying to creating an or. I was putting them together as shown. Could you please let correct me on oring the two expressions together?
Thanks again,
Payam.
