LOL That's OK, (I even corrected your spelling error to make you look better as a sign of goodwill :-). Here's the theological dictionary's definition of "sola Scriptura":
The teaching that the Scriptures contain all that is necessary for salvation and proper living before God.
Now, it is my personal opinion, based on experience, that the real problem that RC's have with the teaching is that is doesn't include their church anywhere in the sentence. LOL
The other problem is denominationalism. There are so many different interpretations of Scripture and no guidance under the common Bible Christian understanding of this theology. Some even lay the responsibility of determining the Cannon on each individual believer and most claim that the individual works out Biblical interpretation through Faith and prayer (a worthy goal). But you've seen these threads...The Baptists disagree with the Presbyterians (on infant Baptism say...) then they gang up on a Pentecostal on fruits of the Spirit etc... Sola Scriptura - by the definition you give - still leaves holes (or is it wholes?) in the fabric of the argument.
