Question: Error when create MapleSim custom component

Hi everyone, I need to use the integral calculation in MapleSim but there is no MapleSim Block to do it. So I create a Custom Component and using the integral calculation from Maple, the expression of the equation was done. But when I click Dimension analysis button, one error popped out as the photo. Have anyone got the same error before? How should I do to solve it? Thank you very much.
