it doesn't seem to work correctly ... it runs into difficulty

These aren't really useful descriptions of the problem, sorry. Since you haven't shown how you are calling the sub, much less provided an SSCCE, it's pretty hard to help.

Update: That said, your sub doesn't return anything, perhaps that's the problem? Without an SSCCE it's still just a guess however.
