Chemical Reaction Revisited

Awhile ago, I had asked how to get a clear to pink reaction and was directed to this site:

http://www.newton.dep.anl.gov/askasci/chem00/chem00370.htm

So, I want to get phenolphthalein and calcium hydroxide.

I looked on this site: http://www.advance-scientific.com/Results.asp?Catalog=phenolphthalein&source=general&go.x=0&go.y=0&go=go

But there are several different phenolphthalein indicators and I don't know which one to get or how much to get. Would I put these in water before mixing them or as is? Suggestions?
