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!

adding a date to a vba code to increase the date each month by 1 month

Asked by andybrooke in Microsoft Access Database, Access Forms, VB Database Programming

Tags: access vba code

I have downloaded a sample database which I have adapted to function to suit its purpose (already with loads of help on this forum)
My last problem is:
on the main form it asks you to input "Date Of 1st Payment"
Then when you press calculate it gives an amorization of payments, HOWEVER I want each row under the column "PaymentDate" to increase each row by one calander month.
I have atached a copy of the database to give an example

if you open the atached database and input the following:

Total Available each Month: £250

Clients total creditors: 10
total Debt: £10000

How Many Qualify For The Plan: £6
Total debt: £6000

Date Of 1st Payment: 01/11/2009

as you will see when you press calculate it inputs the same date "01/11/2009" on each row. I want each row to add 1 month
starting on the 1st row with the date on the main form.
For example.
row 1  01/11/2009
row 2  01/12/2009
row 3  01/01/2010
Etc.
