SetAnalysis : multiple filters

[simonb2013]

My data is a list of table names, field names, key field names 

I have a table, and a measure that works as a logical AND filter.
If a user selects 2 Key Field values, they will see only tables that have BOTH of those fields.

=Sum({<TABNAME = {"=COUNT(KEYFIELDNAME)=$(vKeyFieldsAvailable)"} >} 1)

I can also do this;  the same, but for the 'field' column as opposed to the 'keyfield' column.
=Sum({<TABNAME = {"=COUNT(FIELDNAME)=$(vFieldsAvailable)"} >} 1)

Problem is when I want to use both if these filters together.
I tried this below, but it just results in an error - at least just displays null values.

=Sum({
              <TABNAME = {"=COUNT(KEYFIELDNAME)=$(vKeyFieldsAvailable)"} >
             ,<TABNAME = {"=COUNT(FIELDNAME)=$(vFieldsAvailable)"} >
} 1)

I'm not that confident in the mechanics behind this, so hoping someone can help educate me as to where I'm going wrong !?

Thanks

How about if you try this

=Sum({TABNAME = {"=Count(KEYFIELDNAME) = $(vKeyFieldsAvailable) and Count(FIELDNAME) = $(vFieldsAvailable)"}>} 1)

or if the condition is or, then this

=Sum({TABNAME = {"=Count(KEYFIELDNAME) = $(vKeyFieldsAvailable) or Count(FIELDNAME) = $(vFieldsAvailable)"}>} 1)

Thought this had worked .. apparently not 😞
