VBA to check correct data

Hello Experts,

I am looking for a VBA script to check column A_Material Name = column B_Manufacturer + column C_Model.

1.   If column A is NOT = column B + column C, please highlight these rows in yellow.
2.   If column A is  = column B + column C, please prompt a message " All data in column A_Material Name are cleared"
 
Attached is the sample.

Please help.  Thank You in Advance !

Formula in column D to check:

=A2=B2&" "&C2

Result will show TRUE or FALSE

Formula in E1 to show count of errors:

=IF(COUNTIF(D:D,FALSE)=0,"All data in column A_Material Name are cleared",COUNTIF(D:D,FALSE)&" items outstanding.")

Conditional formatting on data columns to highlight yellow when column D = FALSE:

=$D2=FALSE

Applies to Range:  =$A$2:$D$27544

See attached file.

If you really want a VBA routine then I can work on it.
