search data based on column by inputbox user and mark the cells in the same row

hi
I search for way to search the data based on names in column B .so when I put the name MUSSA into nputbox user then should add oval shape into multiple cells in the same row for each name as 1n sheet case1 , if put the names into inputbox user lke this( MUSSA,MUSS,MUSSIA) then should add oval shape into multiple cells in the same row for theses names . also when run the code should delete oval shape is existed in any cell when inputbox user is empty .
this is what I have so far

HTML Code: 

thanks . the second code what I means , but I would treat the error . if I press cancel or close the inputbox should exit without do anythng .

also when run the code should delete oval shape is existed in any cell when inputbox user is empty .

every time I run the macro should delete the shapes before I search for any name into inputbox .

If Valu = "" Then Exit Sub

thanks again

ActiveSheet.DrawingObjects.Delete

I woundered from this . it doesn't seem to work . it just moves the oval shape from the old name has already been searched to new name which search for it
when I run the inputbox should n't show any oval shape for any cell until it write name into inputbox. every time run the inputbox is empty should dissapear the oval shape.

when run the code by F8 the code works , but when link with button and run it doesn't delete it , also it delete the button despite of use:
Right click on the button
Click on Format Control
Under the properties tab, select Don't move or size with cells
with all of these steps still delete the button

It does delete it.

sorry I was saying it delete it. actually shouldn't delete it to run the code by button .
but I no know why the code works when run f8 step by step it delete the shapes when run the macro . and if I run directly from inside vba editor or by button doesn't delete the shapes when run the macro . also if I add

HTML Code: 

in new macro it will delete it .
I'm so confused

Does Post 9 not make sense?

it's ok . but I'm talking about this

every time run the inputbox is empty should dissapear the oval shape.

let's take this example when search for name it will add oval shape . this step is ok as pic1 , but when run again should be like pic2 not pic3 .
I hope explained my view

@JohnTopley based on post# 14 it's perfect ! many thanks

@sintek based on post#15 it doesn't treat problem deleting the button . so I see the correct is

HTML Code: 

many thanks for your code and time
