InfoPath Dev

I tried this link (http://designshare.wordpress.com/2011/01/11/creating-conditonally-required-fields-in-infopath/) to make my comments box to be filled but only when user select "Rejects" boolean field.  I keep getting infopath contains validation errors.

 I added another rule to the Form Load. where if the modified is not blank and checked the "Don't run the remainder rules if the condition of this rule is met". This seems to be solving the issue. Need to do more testing thou.

 I have added some code in the infopath form on form load where it prevents user to submit acceptance policy twice.  Is there way to ignore this if user is on the list and click on view item?

I have developed a infopath form and it has bunch of validation, rules, etc. All that working fine in Dev. Now it's time to move it to QC or Prod. I saved a copy locally and renamed the xsn file (myFormProd). I opened it in Infopath designer 2010 but did not see an option for Main Data Connection to change it to production url. Please ...
