Xerror mesage

My graphics person up and quit two days ago and I just realized she deleted a whole section of our products out of the cart. They are back in the cart and the new code has been pasted and uploaded through dreamweaver. Everything seems to be working except one part number. Every time we try to add that product we get the following message.

XError: RM1-WBM - $199 is not a valid itemname2 value.

I have checked in the cart control panel and it is showing up in the same format as all other products.

Anyone with any suggestions would be greatly appreciated.

Yes everything is entered through the product manager and then we have interfaces on our site for the actual products. You can go here.

Then on the right side under microphones select RMA-WBM for $199. Add it to your basket and it comes up with the error message listed in the original post.

RM1-WBM - $199 it what is in the cart and how it shows up on the website. I didn't type it exactly in the previous post - just general so everyone knew which one to choose.

I literally copied the code from the product manager and inputted into dreamweaver to be uploaded.

Sometimes the right product shows up for the other ones and sometimes not.

RM1-mics - Pre-Amped Microphones (remove)
This is not supposed to show up like this. The actual product should be listing with it and allow you to purchase it. Sometimes it works correctly and then sometimes it shows like this. I literally have no idea what is going on.

I copied the code directly from the product manager and pasted it in the site. Just don't know what I'm missing.
