Expression Binding Issue - Multiple Math.Rounds

[#1]

Hi experts,

Is it possible to utilize multiple 'Math.round' statements in expression binding? I can't get it working for the life of me.

The following works perfectly;
value='{= Math.round(((${ApplicationModel>Info} / 1000) * ${ApplicationModel>Quantity})*100)/100} {ApplicationModel>UoM}'

But when I add an extra layer of complexity, and have a different calculation depending on the Item type, it doesn't work;

value='{=${ApplicationModel>Item}!=="PV Panels" ? {= Math.round(((${ApplicationModel>Info} / 1000) * ${ApplicationModel>Quantity})*100)/100} {ApplicationModel>UoM} : {= Math.round((${ApplicationModel>Info} * ${ApplicationModel>Quantity})*100)/100 {ApplicationModel>UoM} }'

Any ideas? Is it possible?

Cheers,
Ryan
