Hello, I'm having an error while adding a block.

"An unexpected error occurred. mysqlt error: [1064: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'transitionDuration= WHERE bID=83' at line 1] in EXECUTE("UPDATE btFleggsSlider SET fsID=1,largeWidth=0,largeHeight=0,cropLarge=0,thumbWidth=0,thumbHeight=0,cropThumb=0,randomize=0,useThumbs='true',useArrows=1,transition='fade',autoplay=0,direction='0',delay=,transitionDuration= WHERE bID=83") < Back to Home"

How do i fix this?
