If you can't use numbers with Concat() then use ToString() to convert it to a string
eg. Concat('Value: ', ToString(MYNUMBERPROPERTY)) The expression editor in MapGuide Studio is probably interrogating the capabilities of the current provider to determine what expression functions are available to construct the current expression. If geometric functions aren't there, then it probably means the provider in question doesn't support them. Easy way to find out is to use the mapagent interface, and invoke GetCapabilities on the King Oracle provider. The xml response contains a list of supported expression functions. - Jackie florent wrote: > > Hi all, > > I try to use concat function in MapGuide but i got a error message.
