How to use the rename code to fix my problem?

Dear all

I have a loop procedure (Function loop_test()) to do the function of “perform_auto_analysis()”. When I run loop_test() in the command, there will appear a dialog box asking the pathway (see the attached picture). Then I input the numbers (such as 9 and 9), the procedure will get the results. But when the procedure dose the second loop run, there still appear the dialog box asking the pathway. Thus, my question is how to use the rename code to fix this. Where should I put. Thank you very much.



Function loop_test()
variable BC_n=27, Scat_n=700, lim_BC=28.1, lim_Scat=801
variable/g BC_MASS_CAL
variable/g Scat_cal

do
Scat_n = 700
BC_MASS_CAL = BC_n
do
Scat_cal = Scat_n
perform_auto_analysis()
Scat_n += 25
while (Scat_n < lim_scat)
BC_n += 0.5
while (BC_n < lim_BC)
end



There is not enough information in your post to determine what is displaying the dialog but I believe that it has something to do with missing parameters. Execute this for details:

On another note, you need to use tags so that your Igor code will be properly formatted on IgorExchange. See http://www.igorexchange.com/node/3221 for details.
