Hi, I want to validate the telephone number. I want to allow 0-9, *, +,-,(, SPACE and ). That means it should allow : (240) 643-9325
For that I tried : <var> <var-name>mask</var-name> <var-value>^[0-9()x+. -]*$</var-value> </var> This is working fine. But, I don't have any control in RegEx to check whether user has entered valid set of '(' and ')'. I mean, its allowing : (240( 643-9325 as a valid number. If you have an idea of how to check the sequece of brackets '(' and ')'. Please share it with me. regards, Bakul.
