Hi Tony,

Word has no non-macro facility equivalent to VLOOKUP in Excel. If the values are purely numeric, you could use a formula field (even from outside the table); otherwise, if you're using formfields, you could set the input field's 'calculate on exit' and, possibly, use field coding to achieve the desired result. I'm assuming Excel isn't involved, as nothing in the body of your post suggests anything other than Word table cells are involved.
