Error when using multiple MATCHES string activity one after another

Hi everyone I am having problem when using multiple matches activity in my workflow.
My workflow is like
1.Read Range (Excel)—>I am reading address data from excel row,the pattern in which address is stored is different.
ex 1. 24,London,UK
2. 24 London UK
3. 24.London.UK
2.For each data row—>I am using for each data row and then using matches with regex ,It is working perfectly fine when one matches activity is run single but when i am combining all of my matches with message box it is throwing object refference not set to instance error.

Can anyone tell me how can i use multiple matches inside for each so that i can check each and every row data with matching regex .
