A little Roll20 help?

[B14d3r11]

For the most part you don't need to be 100% familiar with roll20 to understand what I am trying to do. But I am attempting to get two separate scripts to interact with one another. Extended Expressions and ApplyChange for literally 99% of my macro it is using nothing but Extended Expressions the only thing I need is for at the end of the macro be able to call a defined variable from the Extended Expressions side of the macro into the Apply Change side. This would allow me to automate an attack roll and then have it auto deduct the damage from the targeted token's hp. The problem, the variable that defines damage doesn't translate to ApplyChange (Which handles deducting hp) so it isn't treated as actually being worth anything.

Any ideas and thoughts?
