Why was the bet cancelled?

[MICHSTEP]

I submitted a LAY bet on a football market via Excel. Up popped the bet reference in column 20 - everything seemed OK. The "Keep in play" option had been ticked on the interface in case the market might be suspended. A short while later "CANCELLED" appeared in place of the bet reference and the bet was not matched. As I look at Excel now, "LAY" still remains in the trigger cell, the odds and stake cells still have the original values entered.

I am mystified as to why the bet was cancelled. The market was moving in the correct direction for it to be matched. There was no change to the original "LAY" trigger. Anybody shed light on this one, please?

Don't you have to use LAY-IP to keep the bet after the match starts ?

Thanks Ian. I'll try that.
