Currency script installation

[mohitsingh15]

Hi,
I'm going to open up a website using Ashop software(in PHP). {Website of the software is http://www.ashopsoftware.com select free option on the site}. The problem with this software is that is doesn't have the option of my regional currency i.e. Indian Rupees (INR)
I'm targeting Indian customers so I need to display the price in INR. Moreover, I can't use USD as primary option because INR to USD rates changes consistently. So, it may result in the loss of the business.
I guess, extra currency option can be added in this software. Since I'm having very less knowledge in PHP, I'm unable to add the scripting for INR.
Please help me out. I need to launch the website soon. Can anyone provide the script for the same? Or help in other possible ways. Any kind of help will be greatly appreciated. Reply soon.
