Jose, did any of the posts help you with what you needed to solve here, or are you still trying to figure things out? If you need further help, please provide an update and per Arthur's comment, an example app may help a great deal here too. If someone's post did help, please use the Accept as Solution button on that post to give them credit, you can do more than one post as well if multiple posts helped you sort things out. If you did something else completely, consider posting what you did and then mark that as the solution so others will know what worked in this case.
To help users find verified answers, please do not forget to use the "Accept as Solution" button on any post(s) that helped you resolve your problem or question. I now work a compressed schedule, Tuesday, Wednesday and Thursday, so those will be the days I will reply to any follow-up posts.
