And what about HTML-Tags that could be within the String???

Simple, just strip out the characters and everything enclosed within <> using RegExp().
But then again, if I was to use this code, it would be against my own dB entries, and the HTML code would long be removed...
Nice function Jason.

there is a much simplier solution
fullStr="This is some example text To prove the Get teaser function"
function teaser(aStr,aNumber)
tmpArray=split(aStr," ")
redim preserve tmpArray(8)
teaser=join(tmpArray," ")&"..."
end function
don t you think ?
