? you should only have ONE web.config file in the Perfectformsservices folder.
Are you perhaps confusing the <system.web> tag that is the START with the </system.web> tag that is the END
if so, look at the line that is the TOP one and enter the details on the next line.
PS .. don’t set a maxRequestLength of only 100Kb ! that is considerably less than the IIS default of 4Mb (4000Kb) which you can use already without having to make any change
as to how to restart your website in IIS management console – just like you would restart any website. Perhaps talk with your SysAdmin people if you are unsure This will of course involve an interruption of service but when the website has restarted all your connections used in forms will be as they were before
