you have to choose one of the apps and rename the variables,
like strcon, adocon etc...
both have the same variables, so it mess up the logic of the server if you put them in the same page.
Remember that you need to change the names of the variables of the to-be-modified app in all pages.
If you have dreamweaver, put all the pages in a folder and search-substitute the variables in that folder, this way you have to do it only once per app.
and don't forget to make back-ups before anything.
