I just released ver 0.6 of Reservation module.
There was a install bug which I fixed and now it should insert the tables to mysql correctly.
display reservation section in admin panel is still incomplete but the module works if you wanna receive the reservation via mail.
I really sorry for this 0.5 buggy version. Looks like mysql doesn't like utf8.
It should work right now. I also tried with new CMSMS beta 1 and it works.
If you want to use popup calendar please add this code in the header of template.

If calendar still doesn't work maybe you using old browser

Try Firefox. calendar works in IE too but i hate him.
Ouh. about the 1886 error that most of you received. I didn't view this error on my site yet. If someone still receive it with the new version. Please. Send me a link.
I would also like to know if it's possible to have different prices depending on the time of year, and if I could make the reservation period WEEKLY rather than daily.
The module haven't any discounts or different prices. Its just set the price of the room daily.
