Pass Task Sequence Variables to an Application Installation

Hello everyone,

So I am working with my desktop engineer and we are putting together a fairly cool Task Sequence that we haven't done before to future proof the installation of an application. However, we have run across a slight snag and not quite sure how to accomplish it. So here I am coming to all of you guru's.

What I have done is I have created 3 Task Sequence variables and assigned them all the appropriate values. I have gone through the debug capabilities (which as a side note, I would HIGHLY recommend reading up on this if you do any complex work with Task Sequences) and verified that they are in fact that proper values as well. The problem is I go and execute an "Install Application" step and in that step I am attempting to pass them to the installer. Is there a way to do this? (Sorry, looks like it didn't post the full question previously.)

Thanks.
