Don't do it, lol
I'm no expert at vba, but i've learned two things: 1, No special symbols in column headers, and 2, make it all one word. Basically, name your column headers with the same rules that apply to naming variables in vba, I.E. start them with a letter, alphanumeric characters only, no spaces.
Also, be careful with putting an apostrophe (') in any data you'll be using sql on, totally botches up the works.
