Hello,
a Foam::word may not contain spaces and a few other characters.
Use a debugger or add several printf statements to your solver to find the location which causes the error and make sure to use only valid characters.

You're using groovyBC, tight? Older versions had the problem that if there is a space on the left side of the '=' in a variable definition that this error was thrown.
