I can't get a formula I'm putting into my expression box to work.

If I put it in like this xdMath:Eval(., "@Quantity - @LowestCompetitivePrice/@LowestCompetitivePrice") it works, but that's not how I want the formula to work.

I want this: xdMath:Eval(., "(@Quantity - @LowestCompetitivePrice)/@LowestCompetitivePrice"), but as soon as I put those paretheses in, I get the following error:

msxml5.dll
Expression must evaluate to a node-set.

-->(@Quantity - @LowestCompetitivePrice)<--/@LowestCompetitivePrice

Error occurred during a call to property or method 'Eval'.

Can anyone help?

I think the '/' is being misinterpreted. Put a space between @LowestCompetitivePrice) / @LowestCompetitivePrice like so...

Hi,

Try the following expression.
