Difficulty setting animation frame. Yay math!

Howdy, and thanks in advance for any assistance!
Beating my head against a wall today trying to figure out how to express the logic behind my main actives. I am trying to use a little math and 2 global variables to determine the frame number.

Global Value A = 10
Global Value B = 100

A behavior inside the active:
Always -> Force Animation Frame ((Global Value A / Global Value B)*21)
Expected behavior: A number between 0 and 21 based on the percentage generated by dividing the two values being used as the animation frame, the corresponding frame displaying on the screen 'always'.
Actual behavior: Frame stuck at 0.

Other methods attempted:
Build a list of behaviors inside the active conditioned like this : compare two values ((Global Value A / Global Value B) * 21 <1 ---> Force Animation to frame 0, compare two values ((Global Value A / Global Value B) * 21 >= 1 ---> Force Animation to frame 1 etc..
rounding the product of the calculation in case decimals are being interpreted round((Global Value A / Global Value B)*21)
I deleted the active and built it again in case there was a hidden behavior lurking somewhere.

Ideas? Thanks again!

(Global Value A / Global Value B)*21) with Global Value A = 10 and Global Value B = 100
results in
(10/100)*21 = 0.1*21 = 2.1

Edit:: Since you use 10 in stead of 10.0 it will not result in 0.1 but in 0

Maybe best to use the Random expression

Oh how wonderful! So my problem is that I am excluding decimals by not initiating the variable with them, where just before I multiply by 21 anything low is resulting in 0. I cant use random because the two values are contextual. A is a bottles current volume, and B is the same bottles maximum value, there are 21 frames, so basically I am trying to select a frame based on what percentage filled the bottle is. Ill try adding .0 to A and B and see if that helps, Ill check back in a few minutes!

And bam, just like that! The solution: Since you use 10 in stead of 10.0 it will not result in 0.1 but in 0
I added decimals to the variable assigning events and voila everything works as intended now. Mickarrow, im a bang up 3d animator, if u need something, hit me up! Thanks for the help.
