Hi!

I have searched and searched for this problem/bug but without any succes.... so here it goes:

When i try to use "explicit, ALL", on somne formulas, MathCAD substitutes the variables with values so i see the formula with the values substituted, but failes to give me the result and the all formula from which mathcad substitutes is red with the error: "This variable is undefined".

for simple defined variables like this bellow it's ok..

A:=3
B:=2

C:=A+B explicit, ALL -> 3 + 2 -> 5

but when the formula contains variables that come out from other equations or formulas the error i described above appears and despite the fact that he recognize the values for the values he substitues he fails to give me the result
so the equation looks like this:

C:D+F explicit, ALL -> 5 + 2 -> 5 + 2 ...

Is this a bug, or i'm doing something wrong ?

Please help, i really need to explicit my formulas...

Thanks!
