I have a function that copies rows from a "template" spreadsheet then
paste the template information on a number of worksheets as determined
by a cell value. The problem is the macro works fine for the range
(A24:BR52) but doesnt work for (A24:BR55).

By doesn't work I mean the following: The location where the macro is
run from is separate sheet from any of the pasting destinations and
template data (i.e. a third worksheet). Yet when the range hits ~30
lines, the data is pasted into the macro sheet's location --- and into
cells beginning at C16 (a really strange location as the others paste
beginning in A24) -- as well as the proper destination on the other
sheets. Is there a programming error by me or does VB have a
glitch/memory problem??

THANK YOU VERY MUCH FOR ANY HELP -- here is the relevant code, with all
the code appearing at the very bottom.

Sorry to say, but your code is very hard to read.
I would suggest you rewrite it from scratch, using named ranges,
constants and variables instead of all these cell references and row
numbers.
