I did some tests by inserting an '(' character at various places:
If I use on line 20 the code (path= ""; Groovy reports:
Unexpected input: '(path= "";' in index.htt at line number 1 at column number 10
If I use on line 5 the code (folderImgWidthCorrection = Groovy reports:
Unexpected input: '(folderImgWidthCorrection =' in index.htt at line number 1 at column number 64
If I next remove 2 comment lines, so that the error comes on line 3, Groovy reports the same error:
Unexpected input: '(folderImgWidthCorrection =' in index.htt at line number 1 at column number 64
Ignore the line numbers, they are not needed. Copy the error code in the quotes, go to the specified file (index.htt) and invoke the ‘Find’ command. Paste the code, press find and you will be at the location of the error.
