I need Excel VBA programmer

I require an excel VBA programmer for a little assignment .
I have an excel workbook which uses an xer file and loads up data into excel sheet . Everything is working fine all I need is to refine the VBA code to create a button which filters out a specific text from the data and draws the WBS for that matched text entries only . At the moment it draws the wbs for the whole project .

Basically, I have this excel workbook which I got from a friend. It loads up a xer (primavera-P6 file) and draws a WBS structure in excel of all the activates with the relevant columns. It also draws a dashboard alongside the WBS. The above Excel file does that using VBA modules. I have inserted a button named filter which I need to add the code so that when the xer is loaded in Excel. I can filter required information by pressing this button "Filter". For example, if this button is codded for the filtering a particular "activity name" text or string. It should search the temp table find all the activities which match that activity name and display/draw a new WBS according to the filtered activity-name information in a new excel sheet on the same workbook. The code does something similar and by pressing the Gantt chart button draw's a Gantt chart from the loaded xer file but I don't know how to modify the code to draw me another WBS with only filtered activities.
If you look at the VBA files its all commented. I also want a little report on completion about the adjustments in code.
Hope I explained well. Please do not hesitate to contact me for further quires.

Please advise .
Cheers
