Creating a table based on value variables in ModelBuilder

Hi,

I'm trying to get rows in a table populated with values defined by an end-user. The user will have three boxes to enter two double fields and a yes/no or string field and then I want these values to be parsed to a table.

I've been trying to create a solution in ModelBuilder (the end goal being a published geoprocessing tool I can consume via ArcGIS Server), with Value Variables but I've not been having much success.

I have looked through various forum articles and ESRI help files, but would appreciate any further assistance (as many of the solutions I've seen have been for selecting values from pre-existing tables, which is not the case in my scenario).

Thanks,
Karl
