success!
okay. so if anyone else happens to need this function this is what I did.
First I went to devot-ee and searched under the “truncate” tag
http://devot-ee.com/search/tags/tag/truncate/
I tried two plugins
The first was truncHTML
http://devot-ee.com/add-ons/trunchtml/
worked great but it was missing [at the time of this post] a feature that I needed.
I needed the ability to truncate at the last complete word so the character limit didn’t cut off a word if it reached its limit.
I gave Power Truncate a try
http://devot-ee.com/add-ons/power-truncate/
and it worked like a dream and was easy peasy to set-up.
EE + plugins save the day!
