Working in Laserfiche Forms 10, I am getting the following error when I submit a newly created form.

Laserfiche Forms has encountered a problem.

A parameter was not a valid value. [LFF1004-InvalidParameterValue]

No instance is created in the Forms Process Instance Monitoring for this submission to troubleshoot or the event viewer under windwos application or Laserfiche Forms.

I've removed all logic from the workflow other than to save the document to Laserfiche.

I can find no instances of this error in answers or the support site.

Help!!

After much work I found out the issue is being generated from an equation in my form that does not have a computed answer. My Form changes between two layouts, based on a user selection, each of those selections has an equations. Although it only appears to compute the answer from the layout that the person picks and completes it is also trying to compute the other which it cannot as the form was not filled out. I figured this out by completing one layout and then switched to the other form and completed it before submitting, and it worked. As the users only choose one of the two layouts, one formula is never computed but they don't see that. I've reorganizing the form and used IF statements to move from 2 formulas to one. The challenge with IF statements is if any part of the formula cannot be computed it throws an error. This leads to the requirement that each Variable used in an IF Statement needs to have a default value as a minimum, if not an assigned or calculated value. Hope this helps.

Final comment, found out this was all caused by adding two number together by using the format:

=1st_Variable_name+2nd_Variable_Name

instead of using the format

=Sum(1st_Variable_Name,2nd_Variable_Name)

Hi, I can reproduce your issue, we will enhance the error handling for formula

Same exact thing happened to me. When that field wasn't even showing in the form because of field rules. Fixed the calculation format, every went through.

Removing all Logic from the Process down to the point where it's just Start and End produces the same error. IE, Chrome and Firefox all produce the same error.

Check to make sure that the user that is submitting the form has the proper permissions on the folder to which the form is being saved in the repository. Also check to make sure that there are no errors regarding the data type being entered into the metadata fields.

I checked the LFForms Folder as well as the destination folder for permissions. At this point I don't have a process so I believe it should just be submitting to the default forms folder but no such luck.

I am having this same error with one of my fields. I have replaced all of the operators with formula functions, but still getting the error. The field returns the correct value just as I expect it to. I will note that all but one of referenced fields is hidden but all of those hidden fields always have a value in them.

Formula: =IF(AND(App_Type_Selection<2,Current_Date_Serial_Hidden>March_2_Serial_Hidden),(MULT((MULT(SUM(Flat_Lic_Total_Hidden,Late_Filing_Penalty),0.08)),(DIV(SUB(Current_Date_Serial_Hidden,March_2_Serial_Hidden),365)))),0)

Figured this out on my own. So the formula shown above references text fields that were basically just held date serial numbers for me to use in certain calculations. Once I replaced those with the actual formula to compute the date serials inside the formula shown above it worked.
