cck_map warning: array_merge()

Hi,

After trying to submit a map. I got this result and not the map-place where the marker should be.

warning: array_merge() [function.array-merge]: Argument #1 is not an array in /public_html/modules/cck_map/cck_map.module on line 264.

Please assist?
Thanks in advance,
greetings,
Martijn
