Scripting to Upload from an Excel sheet into a web page using load runner

Hi,

I need to script a scenario in load runner wherein i click on an upload button on a web page and specify the path of the excel sheet form where data has to be taken from.The excel sheet is placed in one of the drives of the sytem.Please let me know what protocols i need to use for this in addition to http.
When i record with single protocol(http), replay fails.

Thanks,

HI LA_TSTENG,

IF http fails try URL recording settings.

I'm assuming that all the other parameterization and correlation has been done.
