Why these two variables definition in Matrices of two sheets are different?

[MC盗版用户]

I want to define some variables and align them, so i put them in one matrix just like attached picture.Now there is a problem:I can not remember which day I wrote dowm this in the sheet ,in where this kind of variables definition is valid and I can get the 2nd variable's value below the matrix.but today,in a new sheet when I do this again, it says the variable is not defined, so I cant get the 2nd variable's value below the matrix.whatever i do, this problem remains, but in the valid sheet it is always OK.Could anyone help me?

my MC is "Mathcad 15 F000"

On the top menu line, choose Tools/Worksheet Options/ select the Compatibility tab and where it says Multiple assignment: click the MC11 radio button.

May be it is because the valid sheet is copied from office computer and the invalid is created on my PC ,their Compatibility setups are different if they are all "Mathcad 15 F000". I will check the MC version of office .
