ShadowChemosh, this is most likely aimed at you again. 
I want to take a value from a field like speed (say its 30).
From there I want to convert it to a tag Value.0 to Value.30
How would I convert a convert a tag Value.0 to Value.30?
I know to use perform pulltags[Value.?] to pull the existing tag but how do I create the new tag on the fly then push it back onto the ability.
In this case I want to take your current walking speed and grant either a swim or climb speed of the same value.
