New site - need to have multiple options for one product

[tim_ver]

I have a site now and will be selling vitamins and several products come in differant pill counts and cost are different also. I tried to use the product options in the admin area and created pill counts for 30/60/90 and added the prices to each, but it does not work right. I give a percentage off also so need to have price and discount change out, depending on the pill count select from the drop down. I found this site below, and it has it how I would like to have this option displayed. How do I get this to work, is there a mod or mods to achive this display?

 

 

Example of what I am after for each -

 

Size: 30 Price: $30.33 $20.33 (If I can also list the % discount that would be nice but not required)

Size: 60 Price: $40.33 $30.33 (If I can also list the % discount that would be nice but not required)

Size: 90 Price: $45.33 $36.33 (If I can also list the % discount that would be nice but not required)

I checked this out and looks like it is only for version 2.3.1. I am using version 2.3.3 now. Is there any other mods /add ons that will get me what I need?

2.3.1 and 2.3.3 is fairly similar so aslong as you add the mod manually by editing files then you should be able to use that add-on. NOTE: Do not use the drop-over file install method.

I tried to do the manual install but when I get to step two the index.php file it says find this around line 142 and I can not find it. Also my index.php file is only 92 lines. Ideas on this as I need this mod added.

I have just opened an index file from a new copy of oscommerce and the index file has about 276 lines and the code needed to be changed starts at line 138. I would suggest that you have done something to alter the index.php file, or you are looking in the admin/index,php file.
