Interactive userform please help

HI,

Thanks for looking at my query. Its really urgent and please help me.
I created a interactive userform. When you open the excel , it will automatically open the userform in which you can input the data which will store in the spreadsheet. I done with that and its working good.
My trouble is, i would like to search and edit based on some criteria. That is in my spreadsheet , if i give the week commencing and week ending , it should automatically pull up all other information and i should able to edit those information.

Please check the attachment

Please help me,
