release agreement versus a promissory note

[docbarnes]

I recently sold my franchise and had to sign a release agreement stating that I would pay corporate and my employees $x and allow the new buyer to take over. Corporate sent me over a promissory note to be paid to two parties: Corporate and the landlord of my lease. After signing the documents, I had already fulfilled the landlord part of the promissory note. What am I liable to pay? Just the corporate part of the promissory note or does the release agreement take precedent over this promissory note. I believe the attorney made a mistake and that the landlord should not have been on the promissory note, but the employees.

My store was in TN. Corporate is in Colorado

Thanks
