Baffled by an error message (can't find the value that's just been entered)

My form is almost ready to go, but we've found a small error that's baffling me.

I've lifted a piece of the dynamic booking form from a sample that came with. It lets you add and remove lines from your invoice table.

Separate from that table is a numeric field (NumDays), which lines from the table multiply against.



The problem occurs when you remove a line from the table, and change the "Number of Days" field (NumDays). An error pops up saying "NumDays" is unknown, and yet it still calculates properly.



I'm lost in trying to figure out why it says the value is unknown when you enter the value. Does this make sense to anyone??

Thanks in advance,

Alan
