CALCULATION ERRORS - shipping and payment modules

Hi, I have just installed Zencart and am changing the Shippin and Payment modules in the admin area. I get the following error. What am I doing wrong?

Payment Modules

Only CC and Cheque installed.

You don't tell us what error you are getting.

What you describe looks like the payment modules control screen.

You decide what modules you need / want, then make them ACTIVE by installing them, and editing their settings according to your needs.

The admin error is:

WARNING: YOU HAVE DUPLICATE SORT ORDERS WHICH WILL RESULT IN CALCULATION ERRORS PLEASE CORRECT THESE ISSUES NOW!

Shipping Modules

Modules Sort Order Action
Flat Rate flat 1
Free Shipping Options freeoptions
FREE SHIPPING! freeshipper 0
Per Item item
Per Unit perweightunit 2
Store Pickup storepickup
Table Rate table
United Parcel Service ups
United States Postal Service usps
Zone Rates zones

Thats what my screen says after I edited options. :unsure:

To be clear these are the only options enabled and they appear in this order:

Flat Rate flat 1
FREE SHIPPING! freeshipper 0
Per Unit perunitweight 2

I am getting the same error in payment modules where I have also installed three and graduated them as 0, 1 and 2 in sort order.

Nevermind i appear to have fixed it :-)
