Filemaker Expert needed, I need to build a seatmap.

We are using Filemaker Pro Advanced [login to view URL] in our company. I'm adding image attachment, as V00X, and will refer to them trough this text. Here is the documentation for FileMaker 18 Web Direct module, that we use. [login to view URL] I need a custom view, which works in FileMaker WebDirect view. The custom view I need is an X/Y grid overlay on top of an image, and I need to add data to specific cells created in the grid. Today we have the gird as an image ( V001 ). In FileMaker, it is presented as a table ( V002 ) You can select A001, as an example and add Equipment and Employee, to the A001 field. I want this to merge into a simpler GUI. The steps I want is the following: 1: To create a seat map I shall first upload an image ( V003 ) 2: When an image is uploaded, then I must in FileMaker GUI write the number of columns and rows. This will be the foundation of the database table. ( V004 ) 3. When the grid is created, we can toggle the grid on and off, so that we can adapt and fine-tune the grid to fit the image perfectly. V005 4. When the grid is saved, we can select a cell, and add employees, and equipment. V006 Only grid boxes with equipment/employees will be shown, others will be invisible. 5. The names of the added employee shall be shown on the box when there is added an employee. V007
