将varchar值'[field]'转换为数据类型int时转换失败

I'm creating a smart list for better viewing of reports.

My problem is when im generating the query below, it fails with this error message "Conversion failed when converting the varchar value 'Field2' to data type int."

This my query

SELECT * FROM (SELECT *, ROW_NUMBER() OVER (ORDER BY [SECCODE]) AS RowNumber 
FROM myDB.mySchema.myView 
WHERE [Field1]<[Field2]) tempTable WHERE [tempTable].[RowNumber]>=1 AND [tempTable].[RowNumber]<=100

The Field2 is from a textbox. I try to put the exact field name but I still get the error.

Please help. Thanks in advance.

    declare @v1 varchar(20);
    
    select cast(@v1 as int)..
    
    
    SELECT * FROM (SELECT *, ROW_NUMBER() OVER (ORDER BY [SECCODE]) AS RowNumber 
    FROM myDB.mySchema.myView 
    WHERE [Field1]<cast([Field2] as int) tempTable WHERE [tempTable].[RowNumber]>=1 AND [tempTable].[RowNumber]<=100
