This is the problem:
The following HTML code fragment contains a reference to an image file called frog.gif and with alternate text set to froggy, but the code as written contains a number of errors. Write the HTML line correctly.
<IMG SCR=frog.gif ALT=froggy>
(Note: this problem is very sensitive to the exact characters that you enter. Adding an extra blank anywhere can cause the grading system to flag your answer as an error.)
My answer: <IMG SCR="frog.gif" ALT="froggy">
which was still incorrect, what am I doing wrong? Thank you.
