I'm trying to combine two javascript functions to occur on the same onfocus form field event. My code is below. I have one script which highlights the current form field div, and another script, coded in the div itself, which is supposed to make some text visible when the form field is also clicked on. If I remove one function, the other will work. But if both functions are in the code, only the highlight function works. Any idea how I can combine the two?
Many thanks!
Josh
