Passing A Variable's Value Into An SQL Statement

I want to build an SQL statement in code which includes the value stored in a string variable where the variable name includes a loop counter.

This is a much simplified example of what I am trying to do:

Dim i as integer
dim Strtable1 as string
dim Strtable2 as string
dim Sqlstring as string
...

Strtable1 = "tblEmployees"
Strtable2 = "tblSales"
...
Sqlstring = " select * from ... where....."

for i = 1 to 10

DoCmd.RunSQL "INSERT INTO " & StrTable & i & sqlstring

Next i

I am not sure how to get the table names stored in the string variables into the SQL statement. When I try the above it looks for a variable named StrTable, not StrTable1, StrTable2 etc.
