I have problems in filtering the predecessor lookup field in my task list form.
I have added a column called "ECR-ID" to my task list. This column is of type "Number" without decimals.
All tasks that belong together do have the same value in this column.
At the time when I open the NewForm.aspx I have a value at hand that is being transmitted via GET variable (e.g. &ECR_rel=18).
Now I want to use the 'fn-GetQueryString()' function from Nintex in order to filter the predecessor lookup field.
So in the settings for the predecessor lookup field I have set the following filtering:
Filter available selections: By a specific value
Where field: ECR-ID
Filtered by value: fn-GetQueryString(ECR_rel)
By doing it this way I expected to get all entries that have the value "18" in the column "ECR-ID" but the lookup field remains empty.
Does anyone have an idea why this isn't working?
Any help is much appreciated!
