For 2021 - online Python 3 training - see ((here)).

Our plans were to retire in summer 2020 and see the world, but Coronavirus has lead us into a lot of lockdown programming in Python 3 and PHP 7.
We can now offer tailored online training - small groups, real tutors - works really well for groups of 4 to 14 delegates. Anywhere in the world; course language English.

Please ask about private 'maintenance' training for Python 2, Tcl, Perl, PHP, Lua, etc.

grid config .int_phase1($i) -column 5 -row $nrectrow -sticky "snew"

expected integer but got "0.1300"  is the error i'm receiving.  It's because of the set int_xc($i) [expr $xc + $l] line but how can i fix it.  I need it to add .13 each time but i keep getting errors grar

No - I think it's the
     incr l 0.1300
that's causing the problem - you can only increment by an integer.  Use a set - expr instead, and you should cure the problem.
