Reusing same variable used in 2 equations - 'ladder scenario'

Hi everyone,

 

I'm modelling a grating panel which consists of I profile load bars with round spacer bars running longitudinally. Essentially, this is pretty similar to a ladder setup.

 

I've set up two equations:

 

1) Number of load bar instances, which is driven by the overall length of the spacer bars (Similar to rungs and ladder bars respectively).

 

2) Spacer bar end spacing, so that the two ends are equally spaced.

 

However, I get this error message:

 

"The variable Bar end spacing @Boss-Extrude3 is already used in the earlier equation and is getting modified. Please reorder or change the equations to avoid multiple rebuilds."

 

Any suggestions on how to resolve this? I basically want to specify just the overall length of the spacer bars and have load bar instances calculated as well as have the end spacings equal.

 

Thanks in advance.
