tcl for split and automesh

hello everyone I am triying to work with tcl

 

I want following things tobe done from programme

 

1.select element by window or specific

2.split those elements

3.select element (probably at the end of split to maintain connectivity between the elements)

4.enter elem size

5.automesh

 

so my programme does splitting of elems but not able to do the automesh

 

I have used foreach command

 

I think problem lies there so can someone have look and suggest me whats the error
