>The value of ('loObj'+LTRIM(STR(m.jx+1))) is "loObj1" and I know that loObj1.FieldCount is numeric. Why do I get an error that the expression is not numeric? I assume it's really .F. as it's not a valid expression, but why? Thanks!

You can not use name expression to get a value, you need to use EVALUATE in your case:

with evaluate('loObj'+LTRIM(STR(m.jx+1))
   for iCount = 1 to .FieldCount
     ...
endwith

You can also use

lnFields = GetPem('loObj'+LTRIM(STR(m.jx+1)), 'FieldCount')
