Problem with Regex

[mehdiab]

hi,
how can i match input string as the below :

Input :
number-number,number-number,...,numb er-number
e.g :
123-456677,24114-7809,345555-900007 (matches)
123-456677,-7809,345555-900007 (NOT matches)

i write the pattern

If you want to match the entire input, you need to anchor your pattern at the beginning and end.
