Hi Stephen, Finally got around to trying something with your Mathcell. I think I have everything set up but it doesn't seem to evaluate any formula. I'm sure it's a school boy error on my part... http://stephenteacher.tiddlyspot.com/#Math%20Force is the tiddler I am using to present the data and as you can see it returns values but doesn't do the calc. http://stephenteacher.tiddlyspot.com/#Math%20Force%20Data Is the data tiddler. Any insight much appreciated. Stephen W -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
