Subtotal Based Shipping "Character Limit"

Under admin > extensions > shipping I installed the "Subtotal Based Shipping module" and like it so far but has some limitations. In the configuration where you can enter the price-to-shipcost it only can allow up to 128 characters in the text box, is there a way to up the 128 limit?

so it will only let me put in the below numbers:

20.00:8.95,30.00:9.95,40.00:10.95,50.00:11.95,60.00:12.95,70.00:13.95,80.00:14.95,90.00:15.95,100.0:16.95,125.0:17.95,150.0:18.9

And I want to put in this amount:

20.00:8.95,30.00:9.95,40.00:10.95,50.00:11.95,60.00:12.95,70.00:13.95,80.00:14.95,90.00:15.95,100.0:16.95,125.0:17.95,150.0:18.95,175.0:20.95,200.0:22.95,250.0:24.95,300.0:26.95,350.0:28.95,400.0:30.95,450.0:32.95,500.0:34.95,200000.0:0.00

Do I need to change something in phpmyadmin?

Yes. You would need to change the limits of the table column from varchar(128) to varchar(255) (i believe 255 is the max)

How can I change the limits of the table column from varchar(128) to varchar(255)? Thanks!

execute the following sql using (say) phpmyadmin on your database

Got it! Thanks a lot!!!
