How to link variables with abaqus slover？

Hi, I'm using abaqus as a slover. There are two models which should be optimize synchronously, so some variables were linked. 
--------------------------------
Acitive       Label         Varname                 Expression
1                 com1_1    m_1_varname_1    
1                 com2_1    m_2_varname_1    m_1_varname_1
--------------------------------
But when the 'evaluate' was conducted, there are errors occured:
--------------------------------
13 Error : Scalar value expected for ( com2_1 (m_2_varname_1) )
14 Warning: Could not set the value of variable ( com2_1 (m_2_varname_1) ) in model ( Model 2 (m_2) )
--------------------------------

I'm wondering whether the slover script didn't support the two models link variables？

--------------------------------
