Word 2008... Remove paragraphs from selection

Greetings experts!.. I’m sure I’m not alone in missing my macros after my recent upgrade to Office 2008.
Here’s what I do::: Before designing marketing material for my client, I compile the latest reviews of his products in MS Word… usually the pasted text from the web has paragraphs/carriage returns (?) at the end of every line… I need help-- an Applescript-- for after I select a block of text in Word… to replace paragraphs with a space… just for the selection mind you…
I know I’ll be a willing Applescript fan… once I get over my lost macros hump.
Thank you sooooo
