Error 5 in text field change - vba

Question

I'm updating and populating a combobox named textoControles after updating another combobox named textoCausas. The first combobox textoControles upadtes itself with its change.
Now, I'm getting error '5' in this scenario:
If I have the table ActiveSheet.Name with no data (empty) and enter data into combobox textoCausas, and then enter a character (just entering any character) on textoCausas, then the error '5' stops the macro.
But, if the table ActiveSheet.Name has any data in the first column and I enter data into textoCausas no error stops the macro.
I need some help to solve this error. Thanks!

It's the IsError function. In VBA it tells if a variant has the value vbError. I wanted to say this yesterday but I couldn't replicate the error. It doesn't seem to result from the Match function. Perhaps, the ListObject doesn't exist on a blank sheet causing an error to occur which doesn't assign a value of vbError to the variant resulting from the test. So, the thing to do is to assign Application.Match(Me.textoControles.Value, ws.ListObjects(ActiveSheet.Name).ListColumns(2).DataBodyRang‌​e to a temporary variable. Precede the line with On Error Resume Next and follow it with If Err Then, and your problem should go away.
