Someone did a bad job modeling that one.

>to convert the Age to Integer in thisstatement?
There problem here is that since it's a text field, if there is any non-numeric values, it'll error your expression.

Using this assumes that there are no non-numeric values.
WHERE CInt(Age)> 12

Covering non-numeric values and NULL values, this is probably what you'll need...

select Age From frmRegistrationCSW Where IsNumeric(Age) and Nz(Age, 0) > 12

FROM frmRegistrationCSW
WHERE IsNumeric(Age) And Not IsNull(Age) And Val(Age) > 12

by the way, frmRegistrationCSW is a table?  (a prefix of frm implies form)

I get CInt is not a built-in recognized name

The type in the query should match the type in the table:

esql = "select Age From frmRegistrationCSW Where Age >= '12'"

But comparisons will not work as you expect if you try to compare text as if they were numbers,

"20"  is greater then "100" alphabetically.

Make the Age a numeric field and keep your existing sql.

Yes, it is a table.  Again bad use of terms throughout this program and database.
