[TYPO3-english] Problem in pdf Generation

[J K]

Hi,

I am new to TYPO3.

I try to use pdf generation with PDF Generator with the htmldoc. But while
click the link index.php?1=6&type=123 it gives the error

"Error while executeing (or trying to execute) htmldoc

maybe the gen_pdf.php script was not executed at all".

I use the php version 5.3.2 - If any problem by this version?

Thanks,
Jeyakumar
