Once again,


if isError(workbooks("abcd.xls").sheets("abcd").range
("cell").value) = true then
do
' your Macro
loop
end if


that was not correct, because the do loop should be
outside the if... otherwise it would be a neverending loop
for sure... however, here it follows:

do until isError(workbooks("abcd.xls").sheets("abcd").range
("cell").value) = false

' your Macro

loop


Maybe use if workbooks("abcd.xls").sheets("abcd").range
("cell").value = "false" instead if in the cell the
word "false" is produced... use the code before if the
cell shows an error...

Obviously there are other issues like a neverending loop
etc. but besides
error-trapping, how could I get this to work?
.

Be aware of that problem... neverending loops are mean if
users don't know how to interrupt them...
