Coupon error code

I have Zen 1.3.7

Trying to set up a coupon on a cart that previously had none.
I have installed the discount coupons module and get this message

Warning: Division by zero in /home/xxxxyz/public_html/xxx/admin/includes/classes/split_page_results.php on line 48
1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '-0,' at line 1

[select coupon_id, coupon_code, coupon_amount, coupon_type, coupon_start_date,coupon_expire_date,uses_per_user,uses_per_coupon,restrict_to_products, restrict_to_categories, date_created,date_modified, coupon_active, coupon_zone_restriction from zen_coupons where coupon_active='Y' and coupon_type != 'G' limit -0, ]
If you were entering information, press the BACK button in your browser and re-check the information you had entered to be sure you left no blank fields.

I cant find a zero anywhere near line 48 in the **split_page_results.php
nor can I find the text "**select coupon_id" anywhere in that file.

Removed the module and reinstalled with no change.
Replaced the file on the server and reinstalled module with no change.

A clue for the clueless would be appreciated.
Thanks

I renamed coupon_admin.php to oldcoupon_admin.php and uploaded coupon_admin.php from the original file set. This gave me a new drop down menu in the Gift Certificate/Coupons tab in the dashboard (which had not been there before.)

I then deleted oldcoupon_admin.php

Next I went to the Configuration tab >> GV Coupons and put the number 20 in both Maximum Discount Coupons per page and Maximum Discount Coupon Report Results per page.

This removed the error message.

I do not know which of my actions removed the error code.

If you set the Maximums to 20 and they were 0, that is part of the problem ...

Reloading the file: coupon_admin.php could have corrected other issues ...

Hello,

Using:
Zen Cart 1.3.8a
Patch: 1::

Had the exact error message as original poster.

I applied the second part of the original poster's solution:
"Next I went to the Configuration tab >> GV Coupons and put the number 20 in both Maximum Discount Coupons per page and Maximum Discount Coupon Report Results per page."

And this solved the problem for me.

Thanks!:bigups:
