it seems that you need to increase some values at your server because it seems to be not enough powerful. Please take a look at the php_error_log file of your server, it could contain useful info about this issue.
We have tested it in different browsers..
What we now also see is that when we fill out a price e.g. 1.20 in chrome it says neatly 1.20 with two decimals. But in firefox it will not show the two decimals then. It makes from 1.20 => 1.2 and that will give problems .. why is firefox handling that differently?
ANd according to the saving problem i really do not understand because we build up this form from nothing to how it now is with all the 214 data submitting areas and in between we could save it .. so i think this is something withing breezingforms..
