Hi there, I have installed the formgenerator on my host site and somehow it is working, I also have installed it on my pc which is php 5 enabled running on Apache 2.2, however whenever I am to input a number in the "enter number of fields" I always get this message "You did not enter a valid number. Please use a number between 1 and 99"
Did I miss something? I prefer to do most of my work on my pc locally and just upload it on my host, how can I make this work?
Thank you for anyone who could help me.
