I am having trouble with an application. I am populating a variable lcReprTable with the result of a choice from a list box (lcNetworkName)

lcReprTable = 'Repr' + alltrim(lcNetworkName)

This is referencing me to the table that I want to do testing with. I am using

AFIELDS(laReprStructure,lcReprTable)

to step through the fields of the table. I then use

lcTemp = laReprStructure(lnCount,1)

to grab the field name. I need to check that the data within the lcTemp field is of numeric type. Otherwise, I need to halt the application. I have tried

if type('lctemp') <> 'N'

but that always returns a false as lcTemp is the field name not the data within the field.

Can someone help me out here? I know that this is simple but I'm just spinning my wheels here.

TIA
