you can have 33 parameters, if you'd like.
You can define CODE and Company parameters as static and assign those values, for example.
[EDIT]
For dynamic values, you can pass CODE and Company in a querystring or via form submission.
To pass it in querystring, your link to the page with IFrame module on it should include ?CODE=123&Company=456 at the end of url.
Then, in IFrame Options, create two querystring parameters, name them whatever you want, but make sure that textbox after dropdown (where you select Pass-through QueryString), has the correct QueryString parameter name - CODE for one and Company for the other. When you save it, the list of querystring parameters should look like:
CODE |
Pass-Through QueryString (CODE) |
Company |
Pass-Through QueryString (Company) |
NOTE: if you DON'T pass that querystring but you have IFrame waiting for it, the IFrame will pass those params WITHOUT value (?CODE=&Company=)
