I was using firefox as a browser in in viewing my the output of the php application i made to the company where i am having my intership now. It was a straight road during the production of the application. But one time when i test if the application is a cross browser application, then one shocking output i didn't expect IE keeps on prompting an error what the big problem is i didn't what how would i trace the error sense i doesn't have "contol+shift+j" to view errors unlike firefox and chrome what ive done first is i trace the script manually huh =( doest work..Then i ask mr.google on how to trace bugs on IE then i got this link link here will sounds ok. I was shocked when i discovered, after all the time ive wasted it is the comma. Well that was an experience then atleast i know now how to debug IE hehehe...I was amaze how powerful the comma is.
