Stata ambiguous abbreviation r(111)

I am trying to draw marginplot using stata12. I am running the following code:

margins, at(FuncVariant =(0(0.2) 1)) over(Platform)

Following is the error:

FuncVariant ambiguous abbreviation r(111);

I have the following variables like 

FuncVariant :
FuncVariant 
FuncVariant_mean
FuncVariant_W

Is that creating a problem?

d FuncVariant*

          storage  display     value

variable name   type   format      label      variable label
--------------------------------------------------------------------------------
FuncVariant     byte   %8.0g                  
FuncVariant_m~n float  %9.0g                  
FuncVariant_W   float  %9.0g

I understood that FuncVariant is dummy variable, so instead I used FuncVariant_W, but it throws error

margins, at( FuncVariant_W =-1(0.2)1) over(Platform)
'FuncVariant_W' not found in list of covariates

For many other variables in the dataset it shows the same error, though the variables are present in the dataset.

Post the exact result of the following command to get a diagnosis of the issue in your data:

d FuncVariant*

To get rid of the issue, turn the Stata variable abbreviation setting permanently off:

set varabbrev off, perm

tl;dr: you probably don't have a FuncVariant variable in your data.
