Syntax Error

Hello,

I am working on a Piezoresistivity, Boundary currents module and a time dependent study. I intend to apply a dynamic pressure load on a circular sensor. I have imported the goemetry from Creo 3.0 using the LiveLink feature for Creo. I also am using the parameter sweep feature of comsol. However, while computing, the following error pops up.

"Error in sweep. The following feature has encountered a problem:
Syntax error in expression.
- Expression: {166*unit_GPa_cf,64*unit_GPa_cf,166*unit_GPa_cf,64*unit_GPa_cf,64*unit_GPa_cf,166*unit_GPa_cf,0,0,0,80*unit_GPa_cf,0,0,0,0,80*unit_GPa_cf,0,0,0,0,0,80*unit_GPa_cf}
- Feature: Time-Dependent Solver 1 (sol1/t1) "

If I disable the parametric sweep feature, the following error pops up,
"The following feature has encountered a problem:
Syntax error in expression.
- Expression: {166*unit_GPa_cf,64*unit_GPa_cf,166*unit_GPa_cf,64*unit_GPa_cf,64*unit_GPa_cf,166*unit_GPa_cf,0,0,0,80*unit_GPa_cf,0,0,0,0,80*unit_GPa_cf,0,0,0,0,0,80*unit_GPa_cf}
- Feature: Time-Dependent Solver 1 (sol1/t1)"

I have not entered such expression anywhere in my file. And have never encountered this problem before using while using comsol 4.4 . What might be the possible reason for these errors? I am unable to proceed because of this error.

Thank you in advance .
