Hey guys.....I'm not real smooth with programming, but I've got some of it done. I need to use the formulas I have in the code, and export the data back into my excel sheet......The first Do-Loop is for the Fixed Point iterations, and the second part is for the NR method. I just need to learn how to make this get me my numbers into the spots on the sheet. I'm not sure what I have is correct(other than the formulas). If you guys can advise me, or show me once...I can probably do my best to carry it on. Thank you, Brad ***Ok, well it didn't let me attach the file...so I'm not sure what to do.... Can anyone help me out still....or maybe direct me to a website??
