Sheetcam to Mach3 Issues

Hi I am using sheetcam to make my g code file but am having issues when I import it into mach3. I have the Mach 3 set as the post but when I load the g code its only about 10 lines and will not show the file in the display screen in mach. I have now clue what settings need to be changed to let me make the correct g code file. Any help would be appreciated.

post a pic of your drawing, and post your g code
