Unsure why one works and ther other does not

[Philosophaie]

Ms = 1.98
Mc = 9.4
G = 6.6
X=1
Y=2
Z=3
vx2 = Math.Sqr(G * (Ms + Mc) / X)
vy2 = Math.Sqr(G * (Ms + Mc) / Y) 'Invalid Procedure call or Argument
vz2 = Math.Sqr(G * (Ms + Mc) / Z)

 

[mikerickson]

When the error occurs, what are the values of G, Ms, Mc, and Y?

Also, variable names like vy2 are hazardous, since it could be a cell reference.

Works fine here.

Is vy2 elsewhere defined?

 

[Philosophaie]

I narrowed it the Y and the Z. I also changed it from vy2 to v2y. Y is a very large # in my program ~1e8 could that have anything to do with it?

 

[Philosophaie]

Solved my own problem Y is negative and you cannot take the sqrt of a negative #!
