Fetching dice value from input fields for roll template

I'm right now creating a sheet for an OSR D&D alike. One of the fields in the attacks let's you put in the damage roll. This damage roll is of course variable. (eg: 1d4+2, 1d6-1, 1d8+0 etc). I try to fetch that value from a field and it just won't roll it. Neither from a template nor standalone roll. I know most D&D sheets manage this, however the explanation on the wiki are a bit cryptic and the entry for roll templates does not hint at this at all. Can someone explain to me how it is done?

The macro that is triggered by the roll button, does it have the inline roll brackets around the attribute for your damage calculation? [[@{damageattributehere}]]

That did it! thank you!

Just to explain this: the logic helpers in rolltemplates only respond to numbers (or rolls which produce numbers) which are inside inline roll brackets. The inline roll bracket creates a number in the correct format to be recognised and responded to.
