Hello everyone,

I'm pretty new to regexes and I've got a small problem. I have the following regex: (?<=lblVacant">(ab )?)([\d,.\/]+)(?=(<\/span>|\s\-)) which should match ose1_DetailEstateData1_lblVacant">06.08.2009 - 30.10.2009</span></td>
ailEstateData1_lblVacant">10.08.2009 - 31.10.2009</span></td>
teData1_lblVacant">ab 10.08.2009</span></td>

I'm testing it on http://www.solmetra.com/scripts/regex/index.php, POSIX, ereg and it gives me REG_BADRPT. Where am I wrong? Im also testing it in regexbuddy or regexplanet...and it work perfectly, but here... I tried to add slashes at the beginning and the end of the regex, no use. Is there smth about PHP, restrictions..smth?

Thank you all in advance!
