Create Misc API

I have a package that currently creates two kinds of receipts using the CREATE_MISC and CREATE_CASH APIs.  I'd like to modify them to add the check number which we store in a descriptive flexfield in attribute3.  I did a little research and thought I could just add p_attribute3 as a param of the APIs, but when I tried that, I got the following error when trying to compile:
PLS-00306: wrong number or types of arguments in call to 'CREATE_MISC' ('CREATE_CASH')

The code below is what works correctly (I have the attribute3 line commented out):

ar_receipt_api_pub.create_misc
