Smartforms "Literals that take up more than one line are not permitte"

Hello,

i have one question create a "smartform" form.  If i press the "check" button in the "SAP R/3 Enterprise" there is no error.

But inthe new SAP System "SAP ECC 6.0"; there is following error "Liiterals that take up more than one line are not permitted."

What can i do?

Thanks
