c_schmitz 2012-04-13 15:58 administrator ~18349	Can you please attach your survey? Thank you.

~~user19295~~ 2012-04-13 16:05 ~18350	Hi, Im unable to do that now as I have had to downgrade to 1.92 so I can send a survey live. I neglected to keep the survey in question as it was only a test. I can reproduce the survey if you wish? Regards, Rich Haynes.

c_schmitz 2012-04-16 09:10 administrator ~18359	Rich, please do. We always need the particular survey that is causing the error.

c_schmitz 2012-04-20 08:43 administrator ~18436	?

~~user19295~~ 2012-04-20 16:02 ~18458	Apologies for the delay. My survey is still live until midnight tonight. I will endeavour to upgrade and recreate the survey for you tomorrow morning. Regards.

c_schmitz 2012-05-02 23:54 administrator ~18558	Any news?

c_schmitz 2012-05-07 09:14 administrator ~18589	Feedback please`?
