debug imacros script

I need to edit this imacro for chrome and chek why it does not work. Pheraps i need to change proxy numbers (if I remove them it works correctly) but I dont know how can I set valid Italian proxy number. I need to change proxy for each visit (I need only 10 visit in 1 day). If you can do this let me know and I send to you the order. The script is: PROXY ADDRESS=[login to view URL] URL GOTO=[login to view URL] WAIT SECONDS=30 URL GOTO=[login to view URL] WAIT SECONDS=18 PROXY ADDRESS=[login to view URL] URL GOTO=[login to view URL] etc... fot 10 times
