Need a report showing what was spent on a particular customer/job; cannot do!

I have used QuickBooks for about 10 years and never had occasion to use customers and jobs. I am helping my daughter setup QuickBooks Pro in her law office. As we entered the checks for this year (to pull reports for the tax man), we entered customer and job for each check written. But, in QB 2006 when we go to the customer center and click on one of them, NONE of the items entered shows up! We removed all filters but, still, nothing shows up. If we pull up the check, it DOES show the customer and job. What are we doing wrong? Quick reports are blank also.

Please help!! We are in trouble here. Please respond by email, if you will so we can get on BlackBerry and just remove the nospam info:

quickbooks{nospam}@jimandsuesmith.com

Thanks, so much!!
