Trying to merge data from spreadsheet into Adobe Designer

[surfnjenn]

I hope someone can help me.  I have spent the last two hours trying to figure a way to a way to merge data that is in an Excel 2007 spreadsheet into a Adobe Professional form.  The form is already created and it has interactive form fields.  I am not an "Adobe expert", so please forgive me if I seem uninformed.  It appears to me that I need to export this data into Adobe Designer?  I have tried doing this with no luck.  Could someone please enlighten me to how I could do this?  Thank you!!
