spires Posted April 24, 2009 Share Posted April 24, 2009 Hi guys. Can someone point me in the right direction for how to do the following, an article or tutorial would be great. I want to input data into field 1, then into field 2. This should then automatically populate field 3 with the results. Example: f1 * f2 = f3 If I then change the value of f1 or f2, f3 will automatically change as well. Example 2: 10 * 10 = 100 I then change f1 1 * 10 = 10 I hope this is clear. I have no idea where to start looking for a solution. So any help would be great.

spires Posted April 24, 2009 Author Share Posted April 24, 2009 Hi guys. I want it to work like this. http://www.businessmobiles.com/comcalc/test2.php However, this only places the value into field 3 when you click onto field 3. I want it to populate as i'm typing. Any ideas please. Thanks Link to comment https://forums.phpfreaks.com/topic/155485-creating-a-dynamic-form-help-please/#findComment-818153 Share on other sites More sharing options...
