Answer» Hi, Just wading thru trying to keep my little mind INTACT. My project is a
calculator. The code:
refreshes database, doesn't display data being entered, but does create the
records (zeroes), prints record.
Im HOPING someone will take a look at this, please.
Below is my code; Yeah, I could have removed a little:
personal calculator
input { text-align:center; }
width=100>
<img SRC="http://localhost/images/yesbutton.png" height=25 width=50 alt="yes
button">
click
http://localhost/images/nobutton.png" height=25 width=50 alt="no
button">[/url]
