The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Validation rule for Access Data Entry

Asked by Rayne in Access Architecture/Design, Microsoft Access Database, Access Coding/Macros

Tags: validation rule, access, duplicate entry

hi,
I have got a table which has an Items column which is the (auto number) primary key. I want to create a validation rule for the Issues table in such a way so that when the user enter a data for the Issues column, he will be only able to add distinct issues under the same ID column. In other words, Issues can repeat in different IDs but can't repeat under the same ID. How can I set up such a validation rule for Issues column in the table?
