How to ignore webservice errors?

How to ignore webservice errors?

I have an app that consumes a web service. My app feeds it a phone number, and the webservice returns the phone info. The problem is, if the phone number is not supported the webservice just returns an error. I am trying to iterate over a list of numbers (imported from an excel file) and I need to ignore the ones that return an error in order to continue processing the rest.
I tried an error handler with a connection to the For Each, but that results in an error for "ambiguous paths".

Any Ideas?

Thank you,

Hi Filipe

Have you tried placing the Web Service Call inside a new user action with an error handles, that doesn't abort the current transaction and exist the action?

Then, call this user action from within the For Each cycle.
