I want to remove the word "Metallic" and the word "Pearl" from a field called "Options" in a table called "Specification" and be left with everything else.
This appears to be a re-post of this thread (http://www.access-programmers.co.uk/forums/showthread.php?t=137527). There is apparently a flaw in some of the early versions of jet that originally shipped with Access 2000 that causes a compile error when the replace function is used in an update query.
Did you try any of the suggestions put to you in that thread, srBooth?
You could also just open your table, select the relevant field, and press ctrl-f. type in the text you want to find, select the replace tab, and type in the replacement text you want for that word (make sure the search is for anywhere in the field). Then hit replace all. It won't fix the problem with your version of access but it would fix this issue if it's a one-off situation.
