Passing Max from one parameter to min of another

[JasonRimkus]

I'm trying to set up dynamic range slicers based on parameters, I have set up 2 parameters (Vol 1 and vol 2), when the user adjusts the slider in vol 1, the start of the series for vol 2 should adjust based on the max of Vol 1

the first level would be 

Vol 1 = GENERATESERIES(0, 20000, 1)

Vol 2 = generateseries(max(max vol1) , max(vol1)+20000, 1)

vol 3...

vol 4.. 

vol 5...

i'm able to calculate the min and max in a measure, but unable to pass that value onto the next "level"

Vol 1 Max = SELECTEDVALUE('Vol 1'[ Vol 1], max('Vol 1'[Vol 1]))
