I am using two different jQuery plugins; one for news logo ticker and another for horizontal text slider.
but only one of them is working at a time when when used in sin
Try arranging your script references:
1) jquery
2) jquery-ui
3) newsticker
and add it to the top of the page before calling any jquery related methods.
Not 100% sure if this will work, but give it a try.
Don't know which version of newsticker you are using, but have a look at this link.
