Find Matched Value In A Range For Named Cell Then Copy Range Cells Below

I need method, using a button, that looks at a cell--say EO2, for example--, looks back on a master worksheet at a specified row and range for a match, then looks at the information from a specified range below the matching cell (The information in this column will either be blank or have an "X" in the cell), and then those rows that do not have an "X" will be hidden in the corresponding rows in the working worksheet. Therefore, if at any time the value in "EO2" ever changes, then it will automatically find a new match and repopulate and hide information as before. About 130 columns will have its own button so that a "query" can be made that depends on the information in a particular cell in that column.

The master worksheet now has matrix of 287 rows and 58 columns. Each row is for an operating procedure and each column shows a job code. An "X" in a coordinate cell for a column/row shows whether that job code is responsible for knowing that operating procedure. So, on the working sheet, an employee's primary job code is given underneath his or her name. When the button is pushed, all the operating procedures not required for a given person will be hidden and only the required ones will remain visible--grouped, if you will. Qualification dates will be easier to see now that the information is consolidated. Whenever someone transfers to a new position, a new code will be inputed on the working sheet. When the button is pushed, a new grouping will result. Any operating instructions that overlap will still have qualification dates, so that information will not need to be transcribed.
