User uploaded mailing lists utilizing record counts and file uploads. Follow

When using a File Upload Item or VDP with EzMerge you will find the option to Enable Record Counts. What this will do is allow you to use a QwikPrice field to count how many records a user has and you can set up a fee for mailings or similar projects.

You can also utilize the Data Template File to provide your buyer with a template they can follow for their mailing lists. 

You will find recordcount in the Variables list when using a QwikPrice Formula.

Here you can see in my example I have provided an example list.

In the screenshot shown there are 313 records, and I've priced each at $1.
