Cannot enter price in VM2 in Joomla 1.7.3

[wahoshi]

I tried asking this question before and cannot find it in this board anymore. Please excuse me if I am placing it in the wrong place.
I installed VM2 in Joomla 1.7.3 and all worked well until I tried to enter prices to items. I could not enter prices. I checked all other settings and they seem to be correct.
I have been using VM for a long time but this is the first time with VM2. I hope I can get it running. I would hate to have to learn another cart system at this stage.
Again, please excuse if this is the wrong board for this and a heads-up would be nice if it is the wrong place.
Any help is appreciated.
