    I am having the invalid double error in the first read of the file using keyvaluestore.
    I am not sure how to check if the read is NULL I tried and I am getting a syntax error.

    If IsNumber(kvs.GetSimple("module_1_Addr))


    Sub Activity_Resume
    Module_1_ADDR = kvs.GetSimple("module_1_Addr")
    Module_2_ADDR = kvs.GetSimple("module_2_Addr"):
    Module_3_ADDR = kvs.GetSimple("module_3_Addr"):
    Module_4_ADDR = kvs.GetSimple("module_4_Addr"):

    End Sub

    Did you try kvs.getobject instead of getsimple

    You can also check whether the key exists before trying to get the value:
    Code:
    If kvs.ContainsKey ("module_1_Addr"Then ...
     
    anOparator and Peter Simpson like this.
