How to export data to multiple csv files?

Question

Hey Scripting Guys,
As stated by the name I'm a novice at scripting.  Typically I'm able to resolve most of my scripting challenges by reading through your site or scouring the internet.  This challenge I haven't been able to resolve.  Please help!!
I'm running a script (posted below) to grab data and export it to a csv file.  My challenge is that I want to run the script daily via task manager and have it create a new csv file either daily or weekly.  I'm having trouble with the scripting
creating a new csv file.  How do I resolve this?  
It would be beneficial to append the date to a standard file name, ex. c:\exportedcsv7-11-2014.csv; the next day it would be c:\exportedcsv7-12-2014.csv; and so on.
Thank you in advance to any assistance.
Respectfully,

Thank you for the information and the tip.  I took your advice and did some research on Strings, something that I do have trouble grasping.  I'm familiar with variables already and feel comfortable using them.  I also need to study .Net which
I totally don't understand. 
Since I appreciate your advice and guidance I'd like to know if I'm on the correct track.  Please look at my breakdown to see if I'm explaining it correctly.
$d=Get-Date
Here a variable is being created using the Get-Date cmdlet, if we execute $d the date will appear
$d.ToString('dd-MM-yyyy')
This converts the date into the format dd-MM-yyyy.
I took the information and tips you provided then came up with this after reading about strings.
export-csv -notype "c:\folder\vmds_$($d.ToString('MM-dd-yyyy')).csv"
The double quotes evaluate the variables.  The single quotes do not evaluate anything they just show what's inside of them (a.k.a. literal string). The $() evaluate the expression in ('MM-dd-yyyy') before writing it.
You are correct I definitely need to strengthen the foundation of my basics.  Thank you for the direction and advice.
