While loops to produce iterations of a taylor series?

For the attached document, my code runs continuously, and never stops. I dont get any output values that I can use. I think the issue might lie in the 'count' variable, but im not sure if i need to change it in the while loop. I'll attach my script file, so you can see what I was thinking. Thanks!
