I have used Spreadsheet::WriteExcel for creating spreadsheet report.
I tried to merge some cells using merge_range() function. 
    $worksheet->merge_range(3,5,9,4,$title, $format); [OR]

    $worksheet->merge_range('E3:I4',$title, $format);

    $worksheet->write('F6',"LANGUAGE",$format);

[download]
it shows the error message like the following

Error: refer to merge_range() in the documentation. Can't use previously merged format in non-merged cell


How to solve this error. if I used write() functions that time only it shows the above error.
if I didn't used any write functions that time cells are merged.
