Fix ERROR: type DataTypeStore has no field val

[staticfloat]

It appears to me that the current definition of DataTypeStore does not have a val field, and instead this code was a typo.

Currently, the language server in VSCode is failing for me with the following backtrace:

ERROR: type DataTypeStore has no field val
