Hi,
What does this warning mean.

any help,as always is greatly appreciated

Thanks

Not an error but something doesn't seem right or imformation to the user that he might not realize. In this case, you call a function from an interrupt so the compiler automatically disabled interrupts in that function so that the local variables won't get trashed if you are in that function and an interrupt occurs and that interrupt calls that same function.

Similiarly, you will see the same kind of warning if you call delay_ms() in an ISR and also in main(). Best thing to do is not to use delay_ms() in an isr.
