Flexisel mode not working

Tried Carousel Banner, but it doesn't work in flexisel mode. Got msg. "Notice: Undefined variable: img_width in /var/www/vhosts/censio.lt/subdomains/test/httpdocs/modules/mod_carousel_banner/mod_carousel_banner.php on line 48 "

I've set up img width and height

Hello Krusso

Are you able to edit this file
/modules/mod_carousel_banner/mod_carousel_banner.php on line 48

.nbs-flexisel-item img { max-width:$img_width; max-height:$img_height;}

edit it to

.nbs-flexisel-item img { max-width:$width; max-height:$height;}

see if that works and do let us know the result.

I've edited, but no effect. At least I don't see any msg. Previous dissappeared. In default mode it works very strange also: one banner below another, not in a row and veeery huge, despite banner's setting.

If the warning message is gone then the code fixed above is works.
Those other thing is other stories. It looks like a jquery conflict issue.
Do you have another module that also use jQuery or maybe your template load it? it's hard to guess if we can't see it live

jQuery version loaded from jQuery UI from Google CDN on template is 1.8.3 Is it possible to solve this confict, since every module for slide shows does not work?

Sorry, mistake Loaded jQuery from Google CDN, version 1.8.3
