How to add parameter argument from user created variable in execute query

I want to add parameters arguments of execute query from variable which have dynamics value. I have created two input variables for dynamic column name “allCol” & dynamic column values “allVal”.
Please find the attached screenshot.

Can you add some more details? I am not able to interpret your question clearly.

The tables are dynamic of sql server database, the number of columns and datatypes are varying so I make variable for array of dynamic column names and datatypes but stuck at PARAMETER Argument of Insert query which can’t accept the variable which we have created for dynamic array
